RESONANCE RAMAN SPECTRA OF LIGHT-HARVESTING BACTERIOCHLOROPHYLL a IN PIGMENT–PROTEIN COMPLEXES FROM PURPLE PHOTOSYNTHETIC BACTERIA

Abstract
Resonance Raman spectra of light-harvesting bacteriochlorophyll (Bchl)–protein complexes from several species of purple photosynthetic bacteria were measured. Some differences in the Raman spectra were found between the Bchl molecules (in the complexes) which give an absorption band in the 870–890 nm region and those which give absorption bands in the 800–850 nm region.
