Abstract: (1513 Views)
The study of changes in fluorescence emission of monomer and excimer bands of pyrene molecule is one of widely used approaches to detect molecules with electron-deficiency. This method is capable of detecting explosive materials and fast screening of suspect substances. In the present paper, using fluorescence spectroscopy of pyrene solution, detection of nitromethane with different concentrations is experimentally investigated. The results show that fluorescence quenching of excimer band, on the contrary to the monomer band, bears a considerable sensitivity for nitromethane detection.
