Infrared and Raman spectra and normal coordinate analysis of disilylchloride

Article abstract of DOI:10.1016/0584-8539(91)80123-Z

Disilylchloride has been synthesized by chlorination of disilane with boron trichloride.FTIR spectra have been obtained of the vapour phase and Raman spectra of the liquid phase of this molecule.The spectra are fully assigned for the first time.A normal coordinate analysis is carried out and the refined force constants are compared to previous works on disilane, disilyliodide and silylchloride.The height of the potential energy barrier to internal rotation in disilylchloride is also evaluated.
