Abstract
The internal rotational barriers of PCB isomers were computed using the quantum mechanical INDO method and corrected for the known deficiencies of this semi—empirical model. Based on the hypothesis that the active molecule must be planar, a correlation coefficient (r2) equal to 0.98 was found between the arylhydrocarbon hydroxylase activation data and the fraction of planar conformers predicted from a Boltzmann like distribution.
