Intervalence Band Stark Effect of the Special Pair Radical Cation in Bacterial Photosynthetic Reaction Centers

The Stark spectrum of the intervalence band of the special pair radical cation in bacterial photosynthetic reaction centers is presented. This spectrum, centered at 2600 cm -1, is odeled using a general treatment of intervalence band Stark effects based on a two-state vibronic coupling model of mixed-valency. The observed line shape can be predicted using… CONTINUE READING
