This can be achieved by studying the angular dependence of the primary charge separation rate in an external electric field as reflected in the Dichroic Excitation spectrum of the electric Field modulated Yield of the prompt fluorescence (DELFY).For RCs from Rb.sphaeroides R-26 steady state, low...
Since the delayed light emission decay curve was rather flat throughout the first microsecond following stimulus light extinction, the ratio of prompt fluorescence intensity to delayed light emission intensity could be closely approximated as the ratio of (a)/(b). This ratio was found to be 165...
