The dipole moments of the following series of tertiary substituted aryl-group VB compounds were measured: ( a ) (C 6 H 5 ) 3 M and (XC 6 H 4 ) 3 M with M = P, As, Sb, Bi and X = 4-F, 4-Cl, 4-CH 3 , 3-F, 3-Cl; and ( b ) (3-XC 6 H 4 ) 3− n PR n with R = C 6 H 5 , 4-FC 6 H 4 and X = F, Cl. These experimental molecular moments are discussed as a consistent set of data that allows the calculation, within the framework of the vectorial additive method, of suitable group moments, bond moments and configurational parameters. |
