Abstract
The contours of five Raman bands of liquid tetramethylsilane have been studied over the temperature range 178–350 K. Two bands were further analyzed to obtain the reorientational and angular momentum correlation times by removing the contributions from nonreorientational broadening and comparing the corrected Fourier transforms of the bands with the reorientational correlation functions calculated using the J diffusion limit of the extended rotational diffusion model. The agreement between the correlation times obtained from the analysis of the two Raman bands and those obtained from the nuclear relaxation study of liquid tetramethylsilane is satisfactory.Keywords
