Constant energy synchronous fluorescence for analysis of polynuclear aromatic hydrocarbon mixtures

Constant energy synchronous luminescence has been developed to improve the selectivity of luminescence techniques. If the authors scan the excitation and emission monochromators simultaneously, synchronized so that a constant energy difference is maintained between the wavelengths, considerable improvements are made over conventional synchronous techniques. The foundational concepts of this method are described, correlating experimental parameters with luminescence theory. Experimental parameters are, therefore, more easily optimized. 6 figures, 1 table.
