Both are based on molecular vibrations; however Raman focuses on scattering of light, along with the change in polarizability of a molecule… FTIR uses absorption of light, and depends on a change in dipole moment.

An example of this are the spectra of chloroform and deuterochloroform -- notice that the two major differences in these spectra are (1) the disappearance of the C-H stretching (3020 cm -1 ) and bending (1220 cm -1 ) in deuterated compound and (2) a shift to the right about 20 cm -1 relative to FTIR stands for Fourier transform infrared, the preferred method of infrared spectroscopy. In infrared (IR) spectroscopy, radiation in the IR region of the electromagnetic spectrum is passed through a gas sample. Some of the infrared radiation is absorbed by the sample and some of it is passed through (transmitted). Attenuated Total Reflectance (ATR) is a sampling method for the compositional analysis of a wide range of solid and liquid materials.

The major difference between an FTIR spectrometer and a dispersive IR spectrometer is the Michelson interferometer. Michelson Interferometer The Michelson interferometer, which is the core of FTIR spectrometers, is used to split one beam of light into two so that the paths of the two beams are different. Fourier-transform infrared spectroscopy (FTIR) is a technique used to obtain an infrared spectrum of absorption or emission of a solid, liquid or gas. An FTIR spectrometer simultaneously collects high-resolution spectral data over a wide spectral range. This confers a significant advantage over a dispersive spectrometer, which measures intensity over a narrow range of wavelengths at a time.

In the first case, the absorbed photon has the same wavelength with the emitted one (Rayleigh scattering), but in the second case, the photon has lost or gained an amount of energy The IR Spectrum Table is a chart for use during infrared spectroscopy.

If you need to find the frequency of a material go to the IR table by compound. As the UV or IR light passes through the sample it is absorbed or reflected depending on the molecules present. The intensity of the light is than measure compared to a calibration curve or standard in order to give a quantitative result.

The infrared spectrum can be split into near IR, mid-IR and far IR. Near IR has the greatest energy and can penetrate a sample much deeper than mid or far IR,

To provide a few examples, one might Infrared (IR) spectroscopy by ATR is applicable to the same chemical or biological systems as the transmission method. One advantage of ATR-IR over transmission-IR is the limited path length into the sample.

2014-06-01 · FTIR spectroscopy. Infrared (IR) spectroscopy uses infrared radiation to measure what fraction of the incident radiation is absorbed at a particular wavelength, which can be used to establish semi-quantitative measures of bone composition (Carden and Morris, 2000, Ferraro and Krishnan, 1990, Griffiths, 1983, Thompson et al., 2009). FTIR, specifically the near infra-red region (NIR) (14000 to 4000 cm-1, alternatively, 800 to 2500 nm or 120 to 375 THz). Some of these approaches include analyzing the FTIR absorbance spectra of oral mucous5 and blood serum6. The objective of this project was to investigate the absorption of varying glucose concentrations Technical Note 101b. Optical Techniques for Chemical Identification.
