Answer to Question #301781 in Chemistry for Nibedita Rudra

Question

What are the selection rules for vibration-rotation Raman spectra?

Answer 1

For vibrational Raman spectroscopy, the gross selection rule is that the polarizability of the molecule should change as it vibrates. The specific selec- tion rule for vibrational Raman spectroscopy is ∆v = ±1, where the ∆v = 1 corresponds to Stokes lines and the ∆v = −1 corresponds to Anti-Stokes lines.
