Spectra of selected carotenoid aād standards andĀ e supplements. a Raman, c absorption and fluorescence spectra of phytoene. b Raman, d absorption and fluorescence spectra of Ī²-carotene. The phytoene absorption maximum isā~ā291Ā nm, which is not resonantly enhanced with a 532Ā nm laser, leading to a lack of peaks in the Raman spectrum. e Raman spectra of lycopene, Ī²-carotene, zeaxanthin, lutein, and a mixture of the supplements with corresponding peak maxima
