Eweg, Jan K.; Mueller, Franz; Bebelaar, Dick; Van Voorst, Joop D. W. published the artcile< Spectral properties of isoalloxazines in the vapor phase>, Reference of 2244-11-3, the main research area is alloxazine vapor fluorescence spectra; isoalloxazine vapor fluorescence spectra.
Spectral properties of two alloxazine and six isoalloxazine derivatives were determined at high temperatures in the vapor phase and compared with spectra observed in solution Vapor phase spectrometry gave primary photophys. properties of the isolated chromophore. Fluorescence lifetimes in the vapor phase were <0.5-18 ns. An intramol. complex existed between the isoalloxazine moiety and its aliphatic side chain carrying a polar hydroxyl group. Direct photodissociation of the mol. in its 1st electronically excited singlet state was not very probable. Photochemistry and Photobiology published new progress about Fluorescence. 2244-11-3 belongs to class pyrimidines, and the molecular formula is C4H4N2O5, Reference of 2244-11-3.
