On the adiabaticity contribution to the rate of outer-sphere electron transfers. Reactions of cytochrome c and related transition metal compounds.
Magnetokinetic effects were observed between 0 and 8 T in electron-transfer reactions of Ru(bipy)3(3+) with ferrous cytochrome c, Fe(bipy)3(2+), Fe(Me4-[14]1,3,8,10-tetraene-1,4,8,11-N4)(solvent)2(2+), and Ru(NH3)6(2+). The effects have been related to the adiabatic character of the reactions and rationalized in terms of a mechanism that incorporates the spin-orbit coupling, hyperfine-coupling, and Zeeman mechanism in the expression of the reaction rate constant.
