Question

different between raman spectra and IR spectra​

Answer 1

Answer:

the differences between Raman and IR spectroscopy: The fundamental principles that govern each method - the Raman effect is weak, resulting from an inelastic raman scattering process that occurs when light interacts with molecules; IR spectroscopy is a stronger technique that relies on absorption of light by molecules.

Answer 2

Answer:

Raman spectra result from scattering of light by vibrating molecules whereas IR spectra result from light absorption by vibrating molecules. Raman activity results from change of polarizability of a molecule whereas IR activity results from changing dipole moment. Raman technique is non-destructive.
