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