MSH: Spectrophotometry in the infrared region, usually for the purpose of chemical analysis through measurement of absorption spectra associated with rotational and vibrational energy levels of molecules. (McGraw-Hill Dictionary of Scientific and Technical Terms, 4th ed),CSP: a powerful method for analyzing substances whether solids, liquids or gases; deals with transitions between vibrational energy levels in molecules, and is therefore also called vibrational spectroscopy; an IR spectrum is generally displayed as a plot of the energy of the infrared radiation (expressed either in microns or wavenumbers) versus the percent of light transmitted by the compound.,NCI: A spectrometric method that determines the type and concentration of elements or chemicals in a sample, based upon the principle that the atoms in a sample will vibrate or rotate at a specific frequency when exposed to infrared light.,NCI: A spectrometric method that determines the type and concentration of elements or chemicals in a sample, based
