✦ Synopsis

This paper presents the results of electron spin resonance measurements on several types of stable aromatic free radicals suspected as intermediates in carbonization.

The radicals studied include phenalenyl, 1-methylphenalenyl, 1-phenylphenalenyl, fluorenyl, 9-phenylfluorenyl, and biphenyleneallyl. The radicals all show remarkable stability at high temperatures. For at least a limited group of compounds, a correlation appears to exist between the planarity of free radical intermediates formed during carbonization and the degree of order of the final graphites.

Previous attempts to interpret the time-resolved electron paramagnetic resonance spectra of photosynthetic bacteria have been based on the premise that electron spin polarization arises in the primary radical pair (P+I-) formed by photoinduced charge separation. The observed spectrum is assumed to b
