Laser based methodologies were developed to distinguish between structural isomers of polynuclear aromatic hydrocarbons. Sharp line spectra in glycerol-water glasses were obtained for pyrene, anthracene, phenanthrene, azulene, 9-methylanthracene, triphenylene, and chrysene. Analyses of known amounts of pyrene and anthracene were unaffected when determined in the presence of complex multicomponent samples. The application of the method for analysis of contaminated water samples without preseparation of the impurities is noted. 2 figures, 2 tables.
