✦ Synopsis

The shape and maxima of these spectra at 830 + 10 nm were the same in all three solvents. The energy of the S, (2 '4)

state was found at 13200 + 300 cm-'. The fluorescence quantum yields of all-tram-g-carotene for the above-mentioned solvents are equal to (O.SkO.2) x 10Vs, (0.8kO.2) x lo-' and (2.OkO.3) x lows, respectively. The results are discussed in terms of energy transfer from the all-trans+carotene S1 state to chlorophylls in vivo.
