Electron paramagnetic resonance determination of a low-lying excited state in Chromatium vinosum high-potential iron protein.

H Blum, J C Salerno, R C Prince, J S Leigh, T Ohnishi.   

Abstract

The temperature dependence of the EPR spectrum of oxidized high-potential iron protein from Chromatium vinosum has been studied. From line width and intensity measurements it is possible to determine the position of the first excited unoccupied state, 160 +/- 10 cm-1 above the ground state orbital.
