The determination of dibenzopyrenes and dibenzofluoranthenes (isomers of molecular weight 302) in complex mixtures has received relatively little attention for several reasons including low concentrations in environmental samples, the number of possible isomers, and the lack of reference compounds for comparison. In this paper they describe the separation and identification of isomers of molecular weight 302 in a coal tar extract. The compounds were isolated from the extract by normal-phase liquid chromatography (LC). Thirteen isomers were identified by using a combination of reversed-phase LC, gas chromatography, gas chromatography/mass spectrometry, and low-temperature (Shpol'skii) fluorescence spectroscopy.
