Аннотация: The involvement of upper electron-excited states as the primary excited states into bioluminescence coelenterates was experimentally verified. A series of fluorescent molecules was used as foreign energy acceptors in this bioluminescent reaction. The fluorescent aromatic compounds - pyrene, 2-methoxy-naphtalene, naphthalene, and 1,Показать полностью4-diphenylbutadiene - were selected, with fluorescent state energies ranging from 26,700 to 32,500 cm(-1). Excitation of these molecules by Forster singlet-singlet energy transfer from S., of bioluminescence emitter and by light absorption were excluded. The weak sensitized fluorescence of three compounds was found in the course of bioluminescent reaction. Energy the upper electron-excited states of the bioluminescent emitter was located around 31,000 cm(-1). Localization of the primary excitation on a carbonyl group of coelenteramide molecule is discussed. Comparison of the primary excitation in bioluminescent processes of coelenterates and bacteria is provided. (C) 2009 Published by Elsevier B.V.
