title: Fluorescence excitation profiles of beta-carotene in solution and in lipid/water mixtures.
abstract: Intrinsic fluorescence from all-trans beta-carotene molecules in solution and embedded in lipid/water mixtures has been observed under laser excitation and its excitation profiles measured. The profiles closely correspond to the absorption spectra. The observations can be explained in terms of a low-lying 1Ag excited state.
