Abstract
The i.r. and Raman spectra of hexachlorodisilane are reported in the frequency range 650–33 cm.–1. The data is found to be consistent with an assignment based on a D3d model. Normal co-ordinate calculations are performed on Si2Cl6 by use of modified simple valence force constants transferred directly from SiCl4 and are found to be useful aid in the vibrational assignments. Splitting of the totally symmetrical silicon–chlorine stretching mode for Si2Cl6 is clearly resolved and five of the predicted seven components, due to the presence of 35Cl and 37Cl isotopes, are observed.Keywords
