Abstract
Heme containing high‐spin ferric ion has been doped into perylene, and EPR orientation studies of single crystals have given: (a) values and orientation of principal axes; (b) ligand hyperfine structure from heme pyrrole nitrogens. Formulas are derived to explain the angular behavior of the ligand hyperfine structure. Certain hyperfine constants are then obtained and related to iron pyrrole nitrogen covalency.
