—It is proposed that the low‐lying. electric‐dipole forbidden A g excited electronic state recently discovered in β‐carotene acts as the energy donor in Förster‐type excitation transfer to antenna Chl molecules folbwing β‐carotene's light‐harvesting function in photosynthesis. The mechanism and conclusion should apply as well to all carotenoid accessory pigments.
