Abstract
Femtosecond time-resolved pump-probe absorption spectroscopy has been used to study the photophysics and photochemistry of 9-cis retinal in aerated hexane. Three excited singlet states (S-3, S-2, S-1) and the l owest tripler start (T-1) have been identified by the SVD analysis of the observed time-resolved absorption spectra. No evidence has been ob tained for a 9-cis --> all-trans isomerization reaction pathway that c ompletes in the excited singlet manifold. (C) 1998 Elsevier Science B. V. All rights reserved.
