Reduction of Mn(3+)-tetrakis(4-methylpyridyl)porphine with albumin observed in resonance Raman spectra.
When the resonance Raman spectra of Mn(3+)-tetrakis(4-methylpyridyl)-porphine are measured in the presence of albumins, the resonance Raman bands of Mn(2+)-tetrakis(4-methylpyridyl)porphine are frequently observed. This reduction of Mn3+ to Mn2+ could be caused by an action of unfolding albumins resulting from heat and/or light.
