Using a stretched polyvinyl alcohol film as a host, electron spin resonance (ESR) of the phosphorescent triplet statesof p-phenylphenol and p-phenylphenolate ion has been studied by changing the pH of the medium as an exampIe OF the appIication of ESR to an aad-base equilibrium.

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
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
