The vibrational spectra of germane and silane derivatives. Part II. Difluoro-, dibromo-, and di-iodo-germane
The Raman spectra of dibromo- and di-iodo-germane have been recorded as well as their gas-phase i.r. spectra, but reliable Raman data could not be obtained for difluorgermane. A normal co-ordinate treatment for the fully protonated molecules is presented and the satisfactory transfer of the force fields to the corresponding deuteriated analogues is discussed.
