Abstract
We discuss to what extent recent vibrational spectra of 14-2H, 15-2H and 14,15-2H isotopically labelled L550 provide evidence for the occurrence of 13-cis, 14-s-trans or 13-cis, 14-s-cis chromophore structures in bacteriorhodopsin's photocycle. The discussion is based on a quantum chemical (MNDO) vibrational analysis of four molecular fragments as models for the retinal chromophore in bacteriorhodopsin.
