| Résumé | The electron paramagnetic resonance (EPR) spectra of CH3CH2C(CH3)2CH2· and CH3CH2C(CD3)2CH2· indicate that at 95 K these radicals exist in a rigid conformation with respect to rotation about the three Cβ-Cγ bonds and that the δ-methyl group (of the ethyl moiety) is gauche to one methyl and to the CH2· group. Analysis of the γ-H hyperfine splittings indicates that in the preferred conformation about the Cα-Cβ bond the SOMO eclipses one of the γ-methyl groups, not the γ-ethyl group. The internal rotation barriers of the CD3 and ethyl groups were estimated to be ca. 4 and 6 kcal/mol from the exchange broadening in the EPR spectra at higher temperatures. © 1985 American Chemical Society. |
