The vibrational spectra and the normal coordinate analysis of thiocarbonye halides /|nby C. R. Subramaniam. -- 260 St. Catharines, Ont. : [s. n.],
Abstract
The infrared and the Raman spectra of eSelF has been obtained
for the first time and has been analysed to give the in-plane
normal vibrational frequencies of the molecule, in the ground state.
A normal co-ordinate analysis has been carried out for the molecules
CSF2, CSClF and eSel 2 using a Urey-Bradley type of potential function
and the elements of the [L] matrix elements, the distribution of
the potential energy in Urey-Bradley space, and the displacement
vector diagrams for the normal modes of vibration for these molecules,
have been obtained.
The bond for~e constants obtained through the normal co-ordinate
analysis, have given some interesting results. The stretching force
constant, Kes ' varies markedly with halogen substitution and the
force constants KeF and Keel also vary with substitution.
