Figure 4.3. 3 A change in dipole moment is required for a vibrational mode to be IR active. Raman signals, on the other hand, due to scattering, occur because of a molecule’s polarizability, illustrated in Figure 4.3. 4. Many molecules that are inactive or weak in the IR will have intense Raman signals. rituals of power wotlk
