BIMOLECULAR ELECTRON TRANSFER REACTIONS IN COUMARIN – AMINE SYSTEMS

S.Bakkialakshmi, M. Shakthi, K.B.Renuga Devi

Abstract

Electron transfer (ET) reactions between excited coumarin dyes and an aliphatic amine, Triethylamine (TEA) donor have been investigated using time-resolved (TR) fluorescence quenching measurements. Time-resolved measurements give the quenching constant (Kq), suggesting dynamic nature of interaction in this system. Fluorescence decay curves have recorded for coumarin without and with Triethyl amine (TEA) and average lifetime values have been calculated and reported.
