Abstract

Abstract Time-resolved molecular fluorescence spectroscopy is presented as a sensitive and selective method for the characterization of mixtures of polynuclear aromatic hydrocarbons in the collision-free vapor phase at elevated temperature, in the condensed phase at room temperature, and at 77 K in a Shpol'skii matrix. This technique is applicable for all three conditions and the quantitative analysis for each component in mixtures has a fairly small error. Also the advantages and disadvantages are discussed for these different enviromnents. Anthracene, pyrone and fluoranthene are used as model compounds.
