Picosecond Kinetics of Events Leading to Reaction Center Bacteriochlorophyll Oxidation

Name: Work Video:
Duration: 3 min 30 s
Description: A transient absorption spectrum has been measured in Rhodopseudomonas spheroides R26 reaction centers. Its salient features indicate that both the bacteriopheophytin and bacteriochlorophyll chromophores play a role in the excited state. Decay of this state yields a rise time for oxidation of the reaction center complex of about 150 picoseconds.
