Schwingungsspektrum und Kraftkonstanten des Tetrakis-trimethylsilyl-hydrazin,[(CH3)3Si]2N-N[Si(CH3)3]2

The vibrational spectra (IR and RAMAN ) have been taken for tetrakis-trimethylsilyl-hydrazine. A complete assignment of all observed bands is given. The silicium-nitrogen vibrations are interpreted in terms of a D_2d configuration. Force constants of the GVFF are computed. The valency force constant of the nitrogen-nitrogen bond is comparable to that of N₂H. This proves the interaction of the silicium atoms with the free electron pairs of the two nitrogen atoms.
