Laser Photolytic Fragmentation-Fluorescence Spectrometry of Nonfluorescent Organic and Organometalllc Molecules


The use of fragmentation-fluorescence spectrometry as an analytical technique for the detection and quantification of nonfluorescent organic and organometallic compounds is described. Radiation from a photolysis laser, usually operated at 193 nm, photodissociates gaseous molecules, converting them into atomic or small molecular fragments which are intensely fluorescent. If necessary, fluorescence of fragments can be induced by a second, “probe,” laser. Limits of detection and precision of one- and two-laser photofragmentation-fluorescence determinations are given. The analytically desirable characteristics of laser fragmentation-fluorescence spectroscopy are described, and future directions for development of the technique are discussed.
