Abstract
The hyper‐Raman spectra of K2SnCl6 crystals were measured for various scattering geometries at ambient temperature. The F2u deformation mode of [SnCl6]2−, which is inactive in infrared and Raman spectra but hyper‐Raman active, was observed at 112 cm−1. The TO and LO frequencies of an F1u species are in good agreement with those obtained in a previous study of the far‐infrared reflection spectrum. A lattice dynamics analysis of the optically active crystal vibrations based on a rigid ion model explains the observed frequencies of all optical modes satisfactorily.Keywords
