    • Abstract

       

      From solvatochromicity of CT-band maxima of complexes of TCNE with methylbenzenes in several apolar and polar solvents the inductive effect parameter,hMe, of the methyl group has been calculated by the Coulson-Longuet-Higgins perturbation theory. From the measured solvent dependence ofhMc, the gas-phase value of the same has been determined to be −0·38 which is comparable with Streitwieser's recommended value ofhMe=−0·50. The higher value ofhMe in the gas phase than in solution has been explained.
