Abstract

Tunable dye lasers have been successfully applied to the two-photon ionization spectrometry of seven anthracene derivatives and five dyes in hexane. The sensitivity depended on the excitation wavelength as well as the molar absorptivity. Detection limits for anthracene, 2-methy!anthracene and 1,6-diphenylhexatriene were as low as 20 pg/ml (1 x 10-10M). The detectability by the dye laser excitation was compared with that by the nitrogen laser excitation.
