Multiphonon resonant hyper-Raman scattering of light by longitudinal optical phonons has been detected for the first time in a CdS crystal. The behavior of the scattering cross sections with increasing number of excited phonons is of an alternating nature, and it is directly the opposite of that in the case of resonant Raman scattering. The difference is attributed to different sequences of intermediate states in the cases of multiphonon
