Abstract excerpt

The effect of an external electric field on the optical absorption spectra of wild-type Rhodobacter capsulatus and two Rb. capsulatus reaction centers that have been genetically modified through site-directed mutagenesis (HisM200----LeuM200 and HisM200----PheM200) was measured at 77 K. The two ge...
