Photochemistry of cyanopolyyne molecules
by - 21 December 2015 (modifié le 5 January 2016)
In-situ irradiation of HC3N molecules in cryogenic matrices with UV laser leads to the formation of longer carbon–nitrogen chains: HC5N, C4N2 ou C6N2. This novel synthesis has also been successfully applied to produce HC7N from the HC5N-C2H2 precursor complexes. Identification of these novel species is performed through IR vibrational spectroscopy, electronic luminescence spectroscopy, isotope labelling, and theoretical calculations. Raman and phosphorescence studies are obtained in collaboration with our colleagues in Warsaw
