摘要：

Optically detected magnetic resonance (ODMR) of the light-harvesting complexes CP43 and CP47 of the spinach photosynthetic machinery revealed triplet stales both from carotenoids and chlorophylls. The triplet state of the only carotenoid present in the complexes (beta-carotene) is observed by ODMR using fluorescence detection (FDMR) in the main chlorophyll emission band in the 680 nm region, and absorption detection in the visible region. Chlorophyll triplet signals arc also obtained by microwave sweeping in the chlorophyll emission and absorption regions. MIA spectra are obtained and discussed for both complexes.
