Vibrational spectra of some pentadeuterophenylsilicon compounds

Abstract

The vibrational spectra of C6D5SiX 3 (X=H, Cl, Br), (C6D5)2SiCl2, (C6D5)3SiCl, and Si n (C6D5)2n (n=4, 5) are reported and assigned. The C6H5/C6D5 isotopic shifts in the lower frequency region (100–600 cm−1) are used to elucidate vibrational coupling effects, which occur between silicon-phenyl and silicon-halogen or silicon-silicon modes.
