    • L are reduced at low temperature. Whether this occurs via a change in the ionization state of this residue or a change in other types of interactions with the chromophore is not clear at present. In any case, at low temperature the photochemistry of G(M201)D/L(M212)H RC becomes more similar to that of M(L212)H RCs (i.e., as if Asp M201 were not present), and one would expect a similar effect in the VDDH mutant. This would make low-temperatures studies on this mutant aimed at further elucidating the relative free energies of the states not particularly useful.

    • In both the VDDH and G(M201)D/L(M212)H RCs, about 15% of the P* decay also occurs by charge recombination to the ground state (Figure 2).

    • L and should lie somewhat closer. Both residues upshift the ring-V keto vibrations of the respective chromophores (by different amounts). The Raman and electron-transfer data are both consistent with the Asp residues being ionized, although the effects of the residues to increase the free energies of the respective charge-separated states do not require this situation.

    • (a) These factors include: (i) the use of equilibrium kinetic models that may not include all the possible relevant states or processes, (ii) changes in temperature (used in Arrhenious analyses) certainly affect more than simply kT, (iii) the mixing between the charge-separated states may not simply be thermal in character (dictated by free energy gaps) but also quantum mechanical in nature (dictated by energy gaps) and thus that small entropic contributions (which are temperature dependent) may be important, (iv) there are likely both dynamic relaxation events and static distributions that may affect the applicable (free) energy gaps between the states.
