Solid-state studies. Part I. Raman- and infrared-active carbonyl stretching vibrations of π-benzenetricarbonylchromium

Abstract

The solid-state Raman- and i.r.-active carbonyl stretching vibrations of π-benzenetricarbonylchromium have been analysed by a factor-group approach. By using the energy factorization and harmonic approximations, force constants were calculated which implied that intermolecular interactions were as important for this crystal as intramolecular interactions. The calculations are consistent with available solution data and with the X-ray data.
