摘要：

Excitation to the lowest singlet state of beta-naphtholate ion in aqueous solution, (by the absorption of the 3371 angstrom light from a 7 nsec pulse of an N-2 laser) is followed within <= 1 nsec by formation of a hydrated electron, e(aq)(-). This process precedes the formation of the fluorescent excited state and competes with it. Increased temperature increases e(aq)(-) formation and decreases fluorescence.
