Abstract
The three Raman Al-bands of trichloromonosilanes HSiCℓ3, DSiCℓ3 are studied in the neat liquid state and in solution (isotopic dilution and inert solvent SiCℓ4). The depolarization ratio ϱ is measured from the integrated strengths. The relaxation times τv and τ2R are deduced from the corresponding correlation functions Gv(t) and G2R(t).
Pure dephasing relaxation is predominant for the vibrational modes; the rotational relaxation appears to be of the diffusional type in SiCℓ4 and nearly free for the neat liquids at room temperature.
