Probing excited-state electron transfer by resonance Stark spectroscopy: 4. Mutations near B(sub L) in photosynthetic reaction centers perturb multiple factors that affect

Article Abstract:

An investigation into the factors that control the rate of B(super *)(sub L) -> B(sub L(super +)H(super -)(sub L) gave quantitative estimates for the perturbations to the charge-transfer distance, d(sub CT), and electronic coupling, V(sub o), that accompany perturbations to the driving force for the reaction. The value of full width at half-maximum of the Frank-Condon weighted density of states was estimated using the crystallographic estimate of 11 A between the centers of B(sub L) and H(sub L) in WT RCs.

Probing excited-state electron transfer by resonance Stark spectroscopy: 3. Theoretical foundations and practical applications

Article Abstract:

Resonance Stark effects are non-classical Stark effects associated with excited-state charge-transfer processes. The theory of resonance Stark effects is generalized in various respects and the equations are modified to allow for the violations of the Condon approximation and to allow for the inhomogeneous contributions to absorption and Stark line shapes.

Intervalence band stark effect of the special pair radical cation in bacterial photosynthetic reaction centers

Article Abstract:

The initial electron transfer reaction in bacterial photosynthesis follows the electronic excitation of a strongly interacting pair of bacteriochlorophylls known as the special pair, or P. The stark spectrum of the intervalence band of the special pair radical cation in bacterial photosynthetic reaction centers is presented.
