Abstract :

Electroabsorption (Stark effect) spectroscopy using dual-phase lock-in detection was applied to the B850 absorption band of the peripheral antenna (LH2) complex from the purple non-sulfur bacterium Rhodabacter sphaeroides strain G1C. Electroabsorption signals due to the electrostatic interaction between pigments and surrounding apoproteins were clearly detected from the phase-retarded signal.
