Abstract
Molar Kerr constants and apparent dipole moments at 25° are recorded for the molecules p-XC6H4·CF3(X = H, F, Cl, CF3), C4F5·CF3, and m-C6H4·(CX3)2(X = H, F) in carbon tetrachloride and the data have been analysed to provide the anisotropic electron polarisability for the CAr–CF3 group. The results are compared with those for CAr–CX3(X = H, CH3, Cl) for evidence of hyperconjugation.Keywords
