Potential energy constants and Coriolis coupling constants, calculated
for cis-dichlorodifluoroethylene, cis-dichlorodibromoethylene and cis
-difluorodibromoethylene, reproduced the vibrational frequencies and f
ulfilled the sum rules respectively. Inertial defect calculated values
for the ground vibrational state of these molecules show good corresp
ondence with the reported values for similar ethylene-type molecules.
