Abstract
Some authors interpret the EPR spectrum inγ-irradiated methanol at 77‡K either by the radical ĊH2OH or by Ċ+ H2. In order to contribute to this question we have calculated the values of the hyperfine splitting constants of this EPR spectrum as a function of the valence angle H-C-H in a CH2 fragment. The comparison of the experimental and calculated values of the hyperfine splitting constant and a discussion of the possible valence angles leads us to the conclusion that the EPR spectrum in irradiated methanol originates from the radical ĊH2OH.
