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.

The molecular structure of chlorophyll a consists of a chlorin ring, whose four nitrogen atoms surround a central magnesium atom, and has several other attached side chains and a hydrocarbon tail formed by a phytol ester. Chlorophyll a contains a magnesium ion encased in a large ring structure known as a chlorin. The chlorin ring is a heterocyclic compound derived from pyrrole.
