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