Ferrocytochrome C

Absolute rate constants for the reaction of ferrocytochrome c with the thiyl radicals derived from cysteine, GSH, penicillamine and N-(2-mercaptopropionyl)glycine were measured by using the technique of pulse radiolysis. The reaction is believed to occur through a one-electron-transfer process, in agreement with the hypothesis that thiols may act as catalysts linking hydrogen-atom- and electron-transfer reactions.

Marcus Inverted Region

Investigations are carried out on the nature of photoinduced electron transfer reactions within some metallo-octaethylporphyrin (zinc octaethylporphyrin and magnesium octaethylporphyrin) donors and acceptor 9-cyanoanthracene in cyanobenzene at 300 K by steady state and time-resolved spectroscopic methods. Acceptor is selectively excited at 366 nm and 374 nm for steady state and time-resolved measurements, respectively, where donor metalloporphyrins possess negligible absorbance. Evidence is found for simultaneous occurrence of Förster's type singlet–singlet energy transfer process along with electron transfer. High exergonic values of Gibbs free energy change for both forward and back electron transfer reactions indicate the possibility of occurrences of these two consecutive processes in the Marcus inverted region.
