Matrix-isolation infrared and computer simulation spectra of M(CH 3) nCl 4− n (M = Si, Ge and Sn) type compounds in the M-C and M-Cl stretching regions

Abstract

The IR spectra of the M(CH 3) n Cl 4− n (M = Si, Ge and Sn; n = 4,3,2 and 1) type compounds have been measured in argon and nitrogen matrices at ~ 15 K. The isotope structures have been observed for most of the M-C and M-Cl stretching bands, and assigned by using the computer simulation technique. Relative displacements of individual atoms have been calculated from the observed isotope shifts.
