Picosecond time-resolved resonance Raman spectra (C=C stretching region) of the 2 '& excited state (S, ) have been measured for B-carotene, three derivatives of B-carotene (f%-apoX-carotenal, ethyl &apo-8'-carotenoate and canthaxanthin), and five carotenoids extracted from photosynthetic bacteria (n
