Abstract

PREVIOUSLY published fluorescence spectra of chlorophyll a in dilute ethyl other solution show a major band with maximum at 668 mµ and a minor band with maximum at 723 mµ., at room temperature1,2; at 77° K in ether–isopentane–ethanol (EPA), chlorophyll also exhibits two emission bands, with maxima at about 684 and 735 mµ3.
