✦ Synopsis

Ruorescence quenching of aromatic molecules by inorganic anions in H20-EtOH mixtures at 300 K has been studied quantitatively. A linear relationship between log k. (kq is the quenching rate constant) and AC (the free energy change in electron transfer) is obtained indicating that the &on-mduced quenching proceeds via an electron-transfer pathway. The potential barrier AG* in the electron-transfer process is also given as a function of AG according to the Horiuchi-Polanyi
