Raman
Spectroscopy is a
vibrational
spectroscopy.
Vibrational
spectroscopy probes the periodic oscillations of atoms within a
molecule. Upon inelastic scattering of monochromatic light from the
molecule, the scattered radiation which is one vibrational unit of
energy different from the incident beam is detected in the form of
Raman spectrum. The frequencies of the vibrational modes represent a
fingerprint of the chemical composition, structure and electron density
distribution of the molecule within a given chemical environment.
