โฆ Synopsis
Using n stretched polyvinyl alcohol f&n as a host, electron soin resonance of phosphorescent trip!et states of s%ed aromatic compounds has been studied. Since the guest mole&s have a tendency to orient biaxially, the determination of the fine structure tensor is rather straightfonvud. The advantage of the present method is discussed in relation with v~ious conwntional methods.

By applying a microwave magnetic field parallel to an esternsl magneric field, ESR of naphthalene, quinosaline, quinoline and isoquinotine in their phosphorescent triplet states has been studied at 77 K. The proton hyperfiie structures in the &II = ?2 transitions were distinctly resolved, especially
