Infrared Spectra of the Germyl Halides

Abstract

The infrared spectra of GeH₃F, GeH₃Cl, GeH₃Br, GeH₃I, and their fully deuterated analogs have been measured. All the fundamental vibrations have been observed and assigned. Normal coordinate treatments based on both simple valence and Urey—Bradley force fields have been performed. For germyl fluoride, unusually large frequency shifts have been observed to accompany the phase transition from gas to solid.
