| Abstract: | Coriolis coupling constants have been calculated from force field computations and used to evaluate the inertial defect of 1,1-dichlorodifluoroethylene, 1,1-dichlorodibromoethylene and 1,1-difluorodibromoethylene. The inertial defect values for the ground vibrational state of 1,1-C12C=CF2 = 0.2450, 1,1-Cl2C=CBr2 = 0.3740 and 1,1-F2C=CBr2 = 0.4190 amu Å2 show corrrespondence with the observed values of similar ethylene-type molecules. |
