TOP - The light harvesting protein, bacteriorhodopsin, depends on conformational changes in the retinal chromophore, shown in pink. Changes in the environment of the retinal in different stages of the photocycle are of considerable interest. Step-scan time-resolved FTIR spectra are used to examine dynamics of protein conformational changes.
