Stark spectroscopy of the Rhodobacter sphaeroides reaction center heterodimer mutant.

Proceedings of the National Academy of Sciences of the United States of America - 1 Aug 1990

Abstract excerpt

The effect of an electric field has been measured on the absorption spectrum (Stark effect) of the heterodimer mutant (M)H202L of Rhodobacter sphaeroides reaction centers, where the primary electron donor consists of one bacteriochlorophyll alpha and one bacteriopheophytin alpha. The electronic absorption spectrum of the heterodimer mutant from 820-950 nm is relatively featureless in a poly(vinyl alcohol) film,...
