Paper Abstract

Phase-resolved total luminescence spectroscopy is described for the spectral finger-printing of three different crude oil samples in cyclohexane and in aqueous solutions of sodium taurocholate (NaTC) micelles. Phase-resolved spectra collected at three different excitation modulation frequencies are compared with steady-state spectra in order to illustrate the effects of fluorescence lifetime selectivity. Each phase-resolved spectrum represents a fluorescence lifetime "window" created by the adjustment of the detector phase setting to suppress scattered light, and the lifetime range of the spectrum is determined by the excitation modulation frequency.
