| Inhoud: |
The 9-phenyl thiaxanthyl radical has been obtained from the corresponding cation. A complete analysis of its E.S.R. spectrum has been achieved by using some deuterated derivatives as well as computer simulated spectra. The unusual ratio of the ortho/para hyperfine splittings (✠) has been interpreted as due to the occurrence of restricted rotation of the phenyl ring. Molecular orbital calculations indicate that the experimental results may be interpreted by assuming the phenyl ring to be twisted from the heterocyclic plane by an angle of about 72°. No significant differences were observed between the values of the spin density distribution calculated with standard p and d models. |
