Analysis of PAHs by Shpol"skii fluorescence spectra in low temperature

Abstract

The factors affecting Shpol'skii fluorescence spectra have been investigated on a spectrofluorimeter coupled with a cryospectral system connected by optical fibres, and quasi-linear spectra were obtained. In combination with the synchronous fluorescence technique, the capability of spectral resolution in Shpol'skii spectra is illustrated. The result indicates that Shpol'skii fluorescence spectra may become a routine analytical tool for PAHs.
