— –Analysis of the effect of β‐carotene and benzoquinone on the decay curves of flash‐induced transients in chlorophyll a solutions in pyridine and isooctane indicates that the formation of quinone radicals proceeds via a ternary complex of solvent, chlorophyll and quinone. It is suggested that the solvent is the source of electrons for this process.
