Abstract
Dipole moments of triphenylmethyl derivatives I-VI with electron attracting functional groups were measured in benzene solution. Comparison with respective methyl and tert-butyl derivatives revealed the moments induced in the phenyl group which are possibly somewhat greater than those induced in an alkyl group. These moments should be accounted for when determining mesomeric dipole moments of acceptor groups from benzene derivatives; however, a quantitative evaluation is not yet possible.
