— The triplet yields of 15 derivatives of riboflavin modified either in position 8 or in the ribityl side chain have been determined. The triplet yields measured range from 0.002 to 0.9. In addition, estimates for the rate constants of the photoreaction with EDTA and for the complex formation constants with EDTA at pH 7.0 are given. Evidence for an interaction in solution of at least the 2′ and 5′ hydroxyl groups of RF with the isoalloxazine ring is presented.
