WebIn infrared spectroscopy, units called wavenumbers are normally used to denote different types of light. The frequency, wavelength, and wavenumber are related to each other via the following equation (1): (1) These equations show that light waves may be described by their frequency, wavelength or wavenumber. WebRaman spectroscopy is based on scattering of incident light at an energy shifted by the vibrational energy ( hν) of the molecule. Vibration modes for the same functional groups are observed at the same wavenumber. Though both are forms of vibrational spectroscopy, IR and Raman spectroscopy differ in some fundamental aspects, as shown in Fig. 4 ...
