7. Raman scattering - (combination light scattering) – nonelastic (with
frequency change) light scattering on environment phonon vibrations.
Was experimentally discovered
in February 1928г. in Calcutta
(India) by Sir Chandrasekhara
Venkata Rāman (Nature, 31
march 1928).
1930 г. – Raman was awarded by
Nobel Prize.

• Vibrational frequencies are characteristic of
chemical bonds or groups of bonds in a specific
molecule: normal modes
• Shifts of Vibrational frequencies are sensitive
to local environment of a molecule, such as
crystal phase, local strain, and degree of
crystallinity
=> A Raman spectrum provides a fingerprint
representing the set of bonds present in the
material
• Relative intensities within a spectrum can
quantify the orientation of a bond w.r.t. the
incoming laser polarization. The concentration of
a substance.
• Raman spectroscopy is complementary to IR.
