Excitation energy transfer pathways and mechanisms in the antenna systems of oxygenic photosynthetic organisms were discussed from the viewpoint of methodology of analyses. Time-resolved fluorescence spectroscopy in the picosecond and femtosecond time range and its analytical method were applied to intact cells of cyanobacteria and one species of cryptophyceae, furthermore, a unique phycobiliproteins of cyanobacteria, APC-B. Finally, the most abundant antenna complex of higher plants, that is, light-harvesting complex II (LHC II) was described in detail on the molecular arrangement of chlorophyll molecules and energy transfer pathways among those molecules.
