Resonance Raman spectrum of β‐carotene

Abstract

Abstract Resonance Raman spectra for β‐carotene in carbon disulphide at room temperature have been measured. The experimental absorption spectrum and excitation profiles were analysed using a three‐dimensional model involving several molecular parameters related to the excited state's structure. These parameters are quite different from those reported previously in the literature. A possible explanation for this discrepancy is proposed.
