| Abstract: | The fluorescence yields and lifetimes of chlorophyll-a-in lipid liposomes and vesicles have been measured in an attempt to understand the light harvesting mechanism of photosynthesis. Concentration quenching of the fluorescence was observed in all systems, the extent depending on the lipid used. The system having the highest half-quenching concentration (7.0 × 10?2 molal) was 3:1 mole to mole mixture of monogalactosyl diglyceride and digalactosyl diglyceride. |
