Abstract
The infrared and Raman vibrational spectra of (Me3Si)(4)Si and (Me3Si) (3)SiSi(SiMe3)(3) as well as of their perdeuterated derivatives have b een measured and assigned with the aid of normal coordinate analyses. SiSi force constants were calculated for these strained molecules. The y are considerably smaller than force constants of disilanes or trisil anes.
