Infrared spectroscopy is not the only means of studying molecular vibrational spectra. Raman spectroscopy entails an inelastic scattering system where only A part of the Power of an incident photon is absorbed by the molecule, and the remaining component is scattered and detected. The Electricity change corresponds to absorbed vibrational Power.[ci

The infrared spectrum of a sample is recorded by passing a beam of infrared gentle through the sample. In the event the frequency of the IR is the same as the vibrational frequency of a bond or selection of bonds, absorption takes place. Assessment on the transmitted light-weight reveals simply how much energy was absorbed at Just about every frequ
