New analytical approaches for determination of 1) tricyclic aromatics, 2) alkenes, and weight % data in Naval diesel fuels are described. Tricyclic aromatics are detected and characterized at concentrations as low as approx. 0.25% in diesel fuels. Various analytical approaches for characterizing alkenes in diesel fuels are also explored, including: 1) chromatographic separation of the alkene fraction in diesel fuels by AgNO/sub 3/ impregnated chromatographic columns, and 2) a /sup 19/F NMR tagging method characterizing alkenes. Finally, a calculative method for conversion of LC-1H NMR molar data to weight % data for each chromatographic fraction in a fuel is described.
