The dipole moments of some methyl derivatives of 3,4-dihydroisoquinoline have been measured in benzene at 25 deg C and the experimental directions determined.The correlation with the theoretical dipole moments of the corresponding benzaldimines supports the view that the 3,4-dihydroisoquinolines can be used as models for the Z conformation of N-benzylidenemethylamines.Moreover, the differences between the dipole moment of 3,4-dihydroisoquinolines and that of the corresponding benzaldimines can be ascribed to conjugation across the -CH2-CH2- bridge.Experimental and calculated values of the methyl replacement vectors are in good agreement.
