Abstract:
The absorption spectra of ferricytochrome c complexes with azide, imidazole and cyanide reduced by trapped electrons at the liquid nitrogen temperature were investigated. Differences have been found between the absorption spectra at T=77 degrees K of cytochrome c complexes reduced by radiation and the absorption spectrum of ferrocytochrome c. These differences are supposed to be due to the axial ligation of the Fe(II) by exogenous ligand. The temperature increase led to the removal of exogenous ligand from Fe(II).
