The excited‐state dynamics of the carotenoid zeaxanthin embedded in synthetic bilayers (see picture) are probed with time‐resolved resonance Raman spectroscopy. Triplet excitons form with significant yield via a singlet fission mechanism when zeaxanthin self‐ assembles into multimers. We propose a functional role for singlet fission in biological systems.
