title: Raman spectroscopy of chlorophyll d from Acaryochloris marina.
abstract: The Raman spectroscopy of chlorophyll (Chl) d isolated from Acaryochloris marina has been measured in the range of 250-3200 cm(-1) at 77 K following excitation of its B(x) band at 488 nm. A peak at 1659 cm(-1) of medium intensity arising from Cz=O stretching vibration in the formyl group 3(1) specific to Chl d was observed clearly. Peaks due to other Cz=O stretching vibrations of the 13(1) keto-, 13(3) ester- and 17(3) groups have also been observed with much weaker intensities. Intense Raman peaks in the range of 1000-1800 cm(-1) are reported and homologous comparison with corresponding Raman shifts of Chl a, Chl b and BChl a are presented.
