Abstract

Complete ^1^H and ^13^C NMR assignments for selected carotenoids from purple and green phototropic bacteria are reported for the first time. Assignments are made for the all‐E isomers of OH‐rhodopin (1, 1,2,1′,2′‐tetrahydro‐ψ,ψ‐carotene‐1,1′‐diol), rhodovibrin (2, 1′‐methoxy‐3′,4′‐didehydro‐1,2,1′,2′‐tetrahydro‐ψ,ψ‐carotene‐1‐ol), anhydrorhodovibrin (3, 1‐methoxy‐3,4‐didehydro‐1,2‐dihydro‐ψ,ψ‐carotene), 2‐ketorhodovibrin (4, 1′‐hydroxy‐1‐methoxy‐3,4,3′,4′‐tetradehydro‐1,2, 1′,2′‐tetrahydro‐ψ,ψ‐carotene‐2‐one) and chlorobactene (5, ϕ,ψ‐carotene).
