Abstract

The transient population of excited electronic states in carotenoids is a fundamental part of the photophysical mechanism by which carotenoids contribute to the biochemical function of the pigment-protein complexes in photosynthetic organella. Whereas the roles of electronic state in the overall relaxation mechanism have begun to emerge [1], the contributions and even the presence of vibrationally-excited levels in the relaxation mechanism has remained largely unexplored. In this study, the vibrationally-excited populations in the in vivo and in vitro carotenoids are examined in real time using picosecond time-resolved anti-Stokes resonance Raman scattering.
