Exposure of manganese(III) porphyrin solutions to 60Co γ-rays at 77 K gave the manganese(II) derivatives, with g<*> (apparent) ca. 6, A(55Mn) ca. 77 G and /D/ >/= 0.3 cm-1.The spectra are very similar to those for MnII derivatives prepared chemically.Weak features in the g=2 region for these complexes were obscured by features from a symmetrical MnII derivative of unknown origin.These features grew in intensity on melting and re-freezing.These results suggest that low-temperature irradiation coupled with e.s.r. spectroscopy may be a suitable technique for detecting MnIII derivatives in biological systems.
