Fundamental Molecular Vibrations from 400 to 50/cm.
Abstract
The results of an extensive investigation of the vibrational spectra in the low frequency region are presented and discussed. Two main lines have been explored: (a) Far infrared spectroscopy has been applied to structure determination of manganese pentacarbonyl halides, of iridium dodecacarbonyl and of the tetravinyl derivatives of Si, Ge, Sn and Pb. Moreover the vibro-rotational Coriolis coupling coefficients and their influence on the thermodynamic properties and on the band shapes have been studied for cyanopropyne. (b) The low frequency lattice fundamentals of chain-like molecules have been investigated. In the case of systems containing hydrogen bonds (HF and HCOOH) dispersion curves and density of the states throughout the first Brillouin zone have been calculated and the propagation of phonons through this kind of crystals has been determined.
