Chlorophyll ring

WebThe general trends in the chlorophyll intersystem crossing rate constants of the triplet spin sublevels may be explained qualitatively by a consideration of the one-center spin--orbit and spin--vibronic coupling activity of the chlorophyll ring system and the effect of side-chain substituents on these coupling mechanisms. Authors: WebChlorophyll is a tetrapirol stain containing green metal atoms and a porphyril ring in the dehydro state. It's a green pigment that coexists with zanthophyll and carotene in the chloroplast. Because methyl takes the place of aldehid in both chlorophyll A and B, they are distinct. Porthyrils and haemoglobin both contain chlorophyll a.
