摘要：

Hyper‐Raman spectra of CsI, CsBr, RbI, and SrTiO3 are measured at room temperature. All optical phonons at the I′‐point of the Brillouin zone can be detected including the longitudinal modes and one silent mode. The results obtained for SrTiO3 are compared with data due to other experimental techniques. Superiority of hyper‐Raman speetroscopy in determining frequencies and linewidths is demonstrated.
