— Chlorophyll RC I is a particular chlorophyll of photosystem I common to all organisms with oxygenic photosynthesis. Its structure could be revealed by'H‐NMR, FTIR, neutron activation analysis, complemented by plasma desorption mass spectrometry data. It has been identified as 13′‐hydroxy‐20‐chloro‐Chl a . Two stereoisomers of Chl RC I have also been isolated and identified. Evidence is presented that chlorination of the pigment does not occur during extraction and that artefacts due to impurities are ruled out.
