An ab initio TDHF calculation of the derivatives of the dynamic polarizability of methane with respect to the non‐totally‐symmetric normal coordinates is performed. The derivative with respect to S 4 shows within a frequency range well out of resonance a remarkable change, even a change of sign. The resulting scattering activity is enhanced by a factor of 50 as compared to the static case.
