THE VIBRATIONAL SPECTRUM OF DIMETHYLSELENIUM DIFLUORIDE AND ITS DEUTERIUM ANALOGUE

Abstract

The vibrational spectrum of dimethylselenium difluoride and dimethyl -$d_{6}$ selenium difluoride is reported. The spectrum is compatible with a molecular geometry of $C_{2}$ symmetry. The fundamentals are selected from among the observed frequencies assuming $C_{2}$, summetry. Two approximate normal coordinate calculations supporting the assignment are reported.
