Abstract excerpt

Near-infrared FT-Raman spectroscopy can be used to measure the vibrations of the bacteriorhodopsin (bR) chromophore without the disadvantage of conventional visible resonance Raman spectroscopy, where the visible excitation drives the bR photoreactions. We utilized this technique to investigate t...
