Abstract
Calculations are made of the frequencies, the form of the normal vibrations, and the constants of the potential energy of displacements of atoms during normal vibrations of germanium halides of the type GeHnX4−n (X=F, Cl, Br, I; n=0 to 2) and their deuterium replacements. For displacements of atoms during normal vibrations a calculation is made of the constants of vibrational-rotational interaction in the molecules GeHX3 and GeX4. The validity of the calculation is confirmed by the way in which the sum rule for the ζ- and τ-constants is fulfilled. The mean-square amplitudes are calculated for tetrahedral molecules GeX4 (X=F, Cl, Br, I). An analysis is given of the strong field of germanium halides GeHnX4−n in connection with properties of the structure of the Ge-halide bond.
