Fig. 2
Comparison of basic photochemical and photophysical characteristics of chlorophyll-a and bacteriochlorophyll-a. The redox middle potential, E m, in dichloromethane and the wavelength of the absorption maxima, A max, in the red and near infrared are also indicated. For comparison, the E m of several characteristic redox couples are also indicated. Redox couples: P680/P680 +: ground state PS-II primary donor; H 2 O/O 2 : water/oxygen; P870/P870 +: ground state bacterial RC primary donor; H 2 O 2 /O 2 : hydrogen peroxide/oxygen; P680 * /P680 +: excited state PS-II primary donor; P870 * /P870 +: excited state purple bacterial RC primary donor
