✦ Synopsis

We have studied the properties of naphthslene molecules in a durene host crystal by means of a computer calculation of the intermolecular interactions. The amazingly large reorientation of the naphthalene molecule upon absorption of a (pseudo-) localized phonon in its photoexcited triplet state appws to be caused by the motion of the methyl groups ofneighbowing durene molecules.
