Question

Rule for pure rotational Raman spectra

Answer 1

Explanation:

For Raman spectra the molecules undergo transitions in which an incident photon is absorbed and another scattered photon is emitted. ... The selection rule for linear molecules is ΔJ = 0, ±2. The reason for the values ±2 is that the polarizability returns to the same value twice during a rotation.
