Chlorophyll d is a form of chlorophyll, identified by Harold Strain and Winston Manning in 1943.[1][2] It is present in cyanobacteria which use energy captured from sunlight for photosynthesis.[3] Chlorophyll d absorbs far-red light, at 710 nm wavelength, just outside the optical range.[4] An organism that contains chlorophyll d is adapted to an environment such as moderately deep water, where it can use far red light for photosynthesis,[5] although there is not a lot of visible light.[6]
