QB TIME-SCALES. “There are two other important timescales to be considered. One is the rate at which the excitation leaves the target molecule and enters the reaction centre (~ 1 ps). The other is the rate at which the excitation in any of the BChl is lost owing to fluorescence relaxation (~ 1 ns). It is this latter rate that the excitation must beat, in its race to reach the reaction centre. Remarkably, the excitation is almost always transferred to the reaction centre faster than it can be lost to fluorescence relaxation.”
