• Phenylxanthyl, phenylthioxanthyl, phenylselenoxanthyl, 9-phenylfluorenyl, dioxadehydrocoranthryl, and their derivatives were studied by the electron spin resonance (ESR) technique, and the odd-electron distribution in the radicals was examined. From the results, the angle between the plane of the phenyl group and the plane of the rest of the molecule was estimated at about 63°. Since these radicals are in equilibria with their dimers, heat of reaction in the system was also determined on two of them. Some discussion of the correlation between the heat of reaction and the molecular shape was undertaken.
