Abstract
The polarized fluorescence spectrum of triphenylene as a guest in a n‐heptane single crystal has been studied at 4 K. The transitions in the fluorescence spectrum are analyzed in terms of known ir and Raman active vibrations in the ground state. A small matrix induced deformation of triphenylene, leading to an in‐plane change of geometry is proposed. Polarization data are analyzed in terms of this model.Keywords
