The i.r. and Raman spectra of p-bis(dimethyl-hydroxy-silil)tetradeuterobenzene have been obtained and compared with data of the corresponding normal compound.Complete normal mode calculations of both -d₀ and -d₄ derivatives have been carried out using a set of valence force constants transferred from suitable molecules and refined to account for the observed i.r. and Raman data.Results of a model calculation, in which substituents are considered as point masses, are also discussed in order to provide a convenient starting point to study the chain conformation of a polymer obtained through polycondensation of the investigated molecule.
