Fluorescence action spectra were determined, both at room temperature and at liquid nitrogen temperature, with various blue-green, red and green algae, and greening bean leaves. The action spectra of algae were established with samples of low light absorption as well as dense samples. Fluorescence at room temperature, with a maximum at about 685 mμ, was for the greater part emitted by a short wave “form” of chlorophyll a, possibly Ca670. To this form energy was transferred from β-carotene, chlorophyll b and phycobilins with an efficiency approaching 100%. The action spectra of blue-green algae suggested the presence of a 650-mμ phycocyanin “form”, which seemed bound more firmly to the photosynthetic apparatus than the bulk of phycocya...
