Effect of aliphatic, Triethyl amine (TEA), and its concentration on fluorescence intensity of coumarin-1, one of the coumarin derivatives was investigated. Spectral investigation of coumarin-1 solution containing compounds showed change in intensity as compared to pure coumrin-1 solution. The variation of fluorescence intensity could be used for determination of aliphatic in quenching region. The average lifetime has been calculated and reported.

Keywords: Coumarin-1, Triethyl amine, lifetime.
