Abstract

A 4 ps, 510 nm laser pulse was used to electronically excite toluene solutions of all-trans-β-carotene, canthaxanthin, and β-8'-apocarotenal. The 430-510 nm electronic absorption band of each carotene bleaches immediately upon excitation and recovers with single-exponential kinetics: τ = 8.4 ± 0.6 ps for all-trans-β-carotene, 5.2 ± 0.6 ps for canthaxanthin, and 25.4 ± 0.2 ps for β-8^'-apocarotenal. The results are discussed in terms of the excited singlet state properties of carotenoids.
