Why raman spectroscopy • information on rotational and vibrational levels • raman effect small but accessible by use of lasers • complementary information to ir spectroscopy. Raman spectroscopy is a form of vibrational spectroscopy, much like infrared (ir) spectroscopy however, whereas ir bands arise from a change in the dipole moment of a molecule due to an interaction of light with the molecule, raman bands arise from a change in the polarizability of the molecule due to the same interaction.
