A Clear-Cut Experimental Method to Discriminate between In-Plane and Out-of-Plane Molecular Transition Moments

摘要

Energy(light frequency)and intensity of electronic and vibra-tional transitions are widely used in structural chemistry.On the other hand,polarization,i.e.,the direction in the molecular framework of the transition moment vectors,is much less studied.This is mainly due to the intrinsic difficulties in making polarization measurements,which need a molecular orientation control.
