Raman and fluorescence spectra of fluoro-organic compounds

Abstract

The results of Raman and fluorescence spectra investigations of fluoroorganic aromatic compounds are presented. We present technique for realizing of qualitative and quantitative analysis of fluoroorganic aromatic compounds on the base of Raman and fluorescence spectroscopy. We propose to applicate the pulsed copper vapor laser for exciting of Raman and fluorescence spectra of fluoroorganic samples. The Raman spectra have been received for a number of compounds as: 1- bromoperfluoroocotane, perfluorodecanoic acid, 1,3,5- trifluoromethylbenzene, hexafluorobenzene, pentafluoropyridine, p-fluoro-DL-phenyl-alanine, m-fluoro-DL- phenyl-alanine, o-fluoro-DL-phenyl-alanine, m-fluoro-DL- tyrosine, 6-fluoro-DL-tryptophan, 5-fluorouracil, 5- Fluorouridine, 5-fluoroindole. On the base of our measurements we have worked out the manner of linear molecule C n F 2n+1 Br length recognizing. Thus, presented technique, based on using of the modern laser sources and registration system of Raman and fluorescence spectra, permitted to identify the different fluoroorganic molecules in mixtures and pure samples.
