Co(phen)3] + is able to attack the buried cluster of HIPIP directly, whereas [Fe-(edta)] - cannot do so and must therefore transfer its electron from long range in a process involving minimal protein activation.

The electron transfer rates in biological systems differ from those between small transition metal complexes in solution because the electron transfer is generally long-range, often greater than 10 A [1]. For long-range transfer (the nonadiabatic limit), the rate constant is... 

Whereas the spot positions carry information about the size of the surface unit cell, the shapes and widths of the spots, i.e. the spot profiles, are influenced by the long range arrangement and order of the unit cells at the surface. If vertical displacements (steps, facets) of the surface unit cells are involved, the spot profiles change as a function of electron energy. If all surface unit cells are in the same plane (within the transfer width of the LEED optics), the spot profile is constant with energy. 

Experimental pK data suggest that eyano substitution can exert substantial long-range effeets on phenol aeidity, but the reason for these effeets is not obvious. If ion-dipole interaetions were to blame, the effeet would fall off with increasing ion (0 ) - dipole (CN) separation. If electron delocalization were responsible, then the effeet would be aeeompanied by eharge transfer between the ionie site (O ) and other atoms in the moleeule.
