✦ Synopsis

The resonance Raman excitation profiles (RREPs) of the v1 and v2 vibrations of fucoxanthin in acetone and toluene solvents have been studied. Fucoxanthin, which is a predominant pigment in marine seaweed and phytoplankton, has several structural differences from carotenoids for which excitation profiles have been determined. The RREPs for fucoxanthin are interpreted in terms of a two-mode model and show a B, value which is approximately 20% lower than for carotenoids like p-carotene and lutein which occur in higher plants. Excellent fits between experimental data and the theoretical model were observed in both solvents.
