The EPR signal of the reduced iron‐quinone complex in a single crystal of Rhodopseudomonas viridis has been investigated as a function of orientation. The results are consistent with P4 3 2 1 2 symmetry. Using the corresponding symmetry relations the directions of the principal axes of the effective g tensor of the iron‐quinone complex were evaluated.
