Transition moment directions and molecular structure of some p-cyano-N,N-dimethylaniline derivatives

Linear dichroism spectroscopy and INDO/S calculations were used to separate, locate and assign low-lying electronic transitions in p -cyano-N,N-dimethylaniline and a number of its derivatives. Structural information concerning the twisting of the dimethylamino group in the ground electronic state was obtained from the values of orientation factors.
