The signal directly recorded, called an "interferogram", represents light output as a function of mirror position. In the functional region there are one to a few troughs per functional group. As with two-dimensional nuclear magnetic resonance 2DNMR spectroscopy, this technique spreads the spectrum in two dimensions and allows for the observation of cross peaks that contain information on the coupling between different modes.

Some excitations, so-called combination modes , involve simultaneous excitation of more than one normal mode.

The phenomenon of Fermi resonance can arise when two modes are similar in energy; Fermi resonance results in an unexpected shift in energy and intensity of the bands etc. The infrared spectrum of a sample is recorded by passing a beam of infrared light through the sample. When the frequency of the IR is the same as the vibrational frequency of a bond or collection of bonds, absorption occurs. Examination of the transmitted light reveals how much energy was absorbed at each frequency or wavelength.

This measurement can be achieved by scanning the wavelength range using a monochromator. Alternatively, the entire wavelength range is measured using a Fourier transform instrument and then a transmittance or absorbance spectrum is generated using a dedicated procedure. This technique is commonly used for analyzing samples with covalent bonds. Simple spectra are obtained from samples with few IR active bonds and high levels of purity.

More complex molecular structures lead to more absorption bands and more complex spectra. Gaseous samples require a sample cell with a long pathlength to compensate for the diluteness. The pathlength of the sample cell depends on the concentration of the compound of interest.

Sample gas concentrations well below ppm can be measured with a White's cell in which the infrared light is guided with mirrors to travel through the gas.

White's cells are available with optical pathlength starting from 0. Liquid samples can be sandwiched between two plates of a salt commonly sodium chloride , or common salt, although a number of other salts such as potassium bromide or calcium fluoride are also used.

Solid samples can be prepared in a variety of ways. One common method is to crush the sample with an oily mulling agent usually mineral oil Nujol. A thin film of the mull is applied onto salt plates and measured. The second method is to grind a quantity of the sample with a specially purified salt usually potassium bromide finely to remove scattering effects from large crystals. This powder mixture is then pressed in a mechanical press to form a translucent pellet through which the beam of the spectrometer can pass.

The sample is first dissolved in a suitable, non hygroscopic solvent. A drop of this solution is deposited on surface of KBr or NaCl cell. The solution is then evaporated to dryness and the film formed on the cell is analysed directly.

Care is important to ensure that the film is not too thick otherwise light cannot pass through. This technique is suitable for qualitative analysis. This is one of the most important ways of analysing failed plastic products for example because the integrity of the solid is preserved. In photoacoustic spectroscopy the need for sample treatment is minimal.

The sample, liquid or solid, is placed into the sample cup which is inserted into the photoacoustic cell which is then sealed for the measurement.

The sample may be one solid piece, powder or basically in any form for the measurement. For example, a piece of rock can be inserted into the sample cup and the spectrum measured from it. It is typical to record spectrum of both the sample and a "reference". This step controls for a number of variables, e. The reference measurement makes it possible to eliminate the instrument influence.

The appropriate "reference" depends on the measurement and its goal. The simplest reference measurement is to simply remove the sample replacing it by air. However, sometimes a different reference is more useful. For example, if the sample is a dilute solute dissolved in water in a beaker, then a good reference measurement might be to measure pure water in the same beaker.

Then the reference measurement would cancel out not only all the instrumental properties like what light source is used , but also the light-absorbing and light-reflecting properties of the water and beaker, and the final result would just show the properties of the solute at least approximately.

A common way to compare to a reference is sequentially: This technique is not perfectly reliable; if the infrared lamp is a bit brighter during the reference measurement, then a bit dimmer during the sample measurement, the measurement will be distorted.

More elaborate methods, such as a "two-beam" setup see figure , can correct for these types of effects to give very accurate results. The Standard addition method can be used to statistically cancel these errors. Nevertheless, among different absorption based techniques which are used for gaseous species detection, Cavity ring-down spectroscopy CRDS can be used as a calibration free method.

The fact that CRDS is based on the measurements of photon life-times and not the laser intensity makes it needless for any calibration and comparison with a reference [3]. Fourier transform infrared FTIR spectroscopy is a measurement technique that allows one to record infrared spectra.

Infrared light is guided through an interferometer and then through the sample or vice versa. A moving mirror inside the apparatus alters the distribution of infrared light that passes through the interferometer. The signal directly recorded, called an "interferogram", represents light output as a function of mirror position. A data-processing technique called Fourier transform turns this raw data into the desired result the sample's spectrum: Light output as a function of infrared wavelength or equivalently, wavenumber.

As described above, the sample's spectrum is always compared to a reference. An alternate method for acquiring spectra is the "dispersive" or "scanning monochromator " method. In this approach, the sample is irradiated sequentially with various single wavelengths. The information at all frequencies is collected simultaneously, improving both speed and signal-to-noise ratio. Another is called "Jacquinot's Throughput Advantage": A dispersive measurement requires detecting much lower light levels than an FTIR measurement.

IR spectroscopy is often used to identify structures because functional groups give rise to characteristic bands both in terms of intensity and position frequency. The positions of these bands are summarized in correlation tables as shown below. A spectrograph is often interpreted as having two regions. In the functional region there are one to a few troughs per functional group. In the fingerprint region there are many troughs which form an intricate pattern which can be used like a fingerprint to determine the compound.

For many kinds of samples, the assignments are known, i. In such cases further information can be gleaned about the strength on a bond, relying on the empirical guideline called Badger's Rule.

Originally published by Richard Badger in , [6] this rule states that the strength of a bond correlates with the frequency of its vibrational mode. That is, increase in bond strength leads to corresponding frequency increase and vice versa. Infrared spectroscopy is a simple and reliable technique widely used in both organic and inorganic chemistry, in research and industry.

It is used in quality control, dynamic measurement, and monitoring applications such as the long-term unattended measurement of CO 2 concentrations in greenhouses and growth chambers by infrared gas analyzers.

It is also used in forensic analysis in both criminal and civil cases, for example in identifying polymer degradation.

It can be used in determining the blood alcohol content of a suspected drunk driver. IR-spectroscopy has been successfully used in analysis and identification of pigments in paintings [7] and other art objects [8] such as illuminated manuscripts.

A useful way of analyzing solid samples without the need for cutting samples uses ATR or attenuated total reflectance spectroscopy.

Using this approach, samples are pressed against the face of a single crystal. The infrared radiation passes through the crystal and only interacts with the sample at the interface between the two materials. With increasing technology in computer filtering and manipulation of the results, samples in solution can now be measured accurately water produces a broad absorbance across the range of interest, and thus renders the spectra unreadable without this computer treatment.

Some instruments also automatically identify the substance being measured from a store of thousands of reference spectra held in storage.

Infrared spectroscopy is also useful in measuring the degree of polymerization in polymer manufacture. Changes in the character or quantity of a particular bond are assessed by measuring at a specific frequency over time. Modern research instruments can take infrared measurements across the range of interest as frequently as 32 times a second. This can be done whilst simultaneous measurements are made using other techniques.

This makes the observations of chemical reactions and processes quicker and more accurate. Infrared spectroscopy has also been successfully utilized in the field of semiconductor microelectronics: Another important application of Infrared Spectroscopy is in the food industry to measure the concentration of various compounds in different food products [11] [12].

PAHs seem to have been formed shortly after the Big Bang , are widespread throughout the universe, and are associated with new stars and exoplanets. Recent developments include a miniature IR-spectrometer that's linked to a cloud based database and suitable for personal everyday use, [15] and NIR-spectroscopic chips [16] that can be embedded in smartphones and various gadgets.

The different isotopes in a particular species may exhibit different fine details in infrared spectroscopy. The reduced masses for 16 O— 16 O and 18 O— 18 O can be approximated as 8 and 9 respectively. The effect of isotopes, both on the vibration and the decay dynamics, has been found to be stronger than previously thought. In some systems, such as silicon and germanium, the decay of the anti-symmetric stretch mode of interstitial oxygen involves the symmetric stretch mode with a strong isotope dependence.

For example, it was shown that for a natural silicon sample, the lifetime of the anti-symmetric vibration is When the isotope of one of the silicon atoms is increased to 29 Si, the lifetime increases to 19 ps. In similar manner, when the silicon atom is changed to 30 Si, the lifetime becomes 27 ps. Two-dimensional infrared correlation spectroscopy analysis combines multiple samples of infrared spectra to reveal more complex properties.

By extending the spectral information of a perturbed sample, spectral analysis is simplified and resolution is enhanced. The 2D synchronous and 2D asynchronous spectra represent a graphical overview of the spectral changes due to a perturbation such as a changing concentration or changing temperature as well as the relationship between the spectral changes at two different wavenumbers.

Nonlinear two-dimensional infrared spectroscopy [18] [19] is the infrared version of correlation spectroscopy. Nonlinear two-dimensional infrared spectroscopy is a technique that has become available with the development of femtosecond infrared laser pulses.
