Abstract
Semireduced acridine orange was generated pulse-radiolytically by reactions of various one-electron reducing radicals (eaq-, (CH3)2COH, CO2-) with the cationic dye acridine orange. Rate constants for the reactions of all these radicals with the dye were determined and the yields of the transient, semireduced acridine orange in these reactions were estimated. Spectral and acid-base properties of the semireduced species formed by these reactions have been evaluated and the nature of its decay kinetics has been resolved. Rate constants for the interaction of the transient with the parent molecule have been determined. Using (CH3)2CO,H+/(CH3)2COH) as the standard couple, the one-electron reduction potential of the dye was determined.
