Molecular relaxation in dimethyldichlorosilane from Raman band shape studies

Rotational and vibrational relaxation of pure liquid dimethyldichlorosilane (DMDCS) at temperatures of 279, 293, 308 and 323 K and in carbon tetrachloride, dioxane, chloroform and cyclohexane solutions at 293 K were studied by Raman band shape analysis. The activation energy for molecular reorientat...

Beschreibung
Zusammenfassung:	Rotational and vibrational relaxation of pure liquid dimethyldichlorosilane (DMDCS) at temperatures of 279, 293, 308 and 323 K and in carbon tetrachloride, dioxane, chloroform and cyclohexane solutions at 293 K were studied by Raman band shape analysis. The activation energy for molecular reorientation of DMDCS molecules was determined. The experimental vibrational correlation functions were compared with the Kubo‐Rothschild and Oxtoby relationships.
