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 C = O stretching vibration in the formyl group 3¹ specific to Chl d was observed clearly. Peaks due to other C = O stretching vibrations of the 13¹ keto-, 13³ ester- and 17³ 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.
