This article reports that tunable, dye laser excitation of Shpol'skii effect spectra provides a potentially useful means of determining PAH compounds directly in coal liquids and shale oil without prior isolation of the PAH fraction by chromatographic or other techniques. The data reported were obtained by selecting excitation wavelengths within the response curve of a single dye, 2-(4-biphenylyl)-5-phenyl-1,3,4 oxadiazole (PBD). The characteristic low temperature excitation spectra of PAH compounds in appropriate Shpol'skii matrices are known to be sharp (FWHM approx. 10cm/sup -1/). The luminescence of four individual PAHs is included. The analytical results obtained for a typical solvent refined coal and shale oil sample are summarized. 2 figures, 1 table. (DP)
