Abstract
Vinyl chloride-d3 has been prepared and the infrared spectrum has been obtained in the region from 400 to 4000 cm-1. The spectrum is compared with the that of vinyl chloride. Normal coordinate analyses are made for vinyl chloride and vinyl chloride-d3. A force field of the Urey-Bradley type is used for the planar vibrations, and a modified valence-type potential function is applied to the nonplanar motions. The vibrational secular equations are set up in the GF matrix fashion. The force constants are determined by a least-square process. The force constants established for vinyl chloride are used to calculate the fundamental frequencies of vinyl chloride-d3. Satisfactory results are obtained.Keywords
