摘要: The ENDOR spectra of Tschitschibabin's hydrocarbon and certain its specifically deuterated derivatives have been measured. To interpret these the factors determining spectrum a biradical are discussed in detail. analysis reveals that paramagnetic species present solutions responsible for solution electron resonance is substituted p-biphenyldiphenylmethyl radical, thus resolving paradox. substituent thought to be diphenylmethyl group which case radical could formed through hydrogen abstraction by thermally populated triplet.
