Abstract
Room temperature fluorescence spectroscopy of petroleum and its processed fractions, coal-derived liquid products and shale oil are reviewed. Conventional fluorescence, synchronous scanning and excitation-emission matrix are covered. The problems that the complexity of different products cause in their fluorescence spectroscopic analysis are discussed. As well as identification of individual polycyclic aromatic compounds, the use of fluorescence spectroscopy to monitor other aspects of these complex materials, for example the source of crude oils, rank of coals (from solvent extracts) and the molecular weight of coal-tar pitches, are examined.
