Anisotropic Proton Hyperfine Interaction in the CH Bond

Abstract

The anisotropic proton hyperfine interaction of the CH fragment is investigated in connection with the properties of the CH bond in aromatic hydrocarbon radicals or ions by the use of the LCAO—MO's determined by the condition of minimum energy. The dependence of the hfs on the bond angle is not as great as that expected from a simple consideration of the s—p hybridizations in the CH bond.
