We establish soliton-like asymptotics for finite energy solutions to the Schrödinger equation coupled to a nonrelativistic classical particle. Any solution with initial state close to the solitary manifold converges to a sum of a travelling wave and an outgoing free wave. The convergence holds in global energy norm. The proof uses spectral theory and the symplectic projection onto the solitary manifold in the Hilbert phase space. 相似文献

The photolysis of aqueous solutions of two widespread environmental organic ecotoxicants—phenol and 4-chlorophenol—on excitation by UV radiation from a KrCl exciplex laser and a glow-discharge KrCl excilplex lamp was studied. The irradiated solutions were studied by spectroscopic techniques. The laser and lamp photolyses were compared. 相似文献

Conclusions The reaction of N-acetylthiourea with phenyl and p-tolyl radicals leads to diaryl disulfides and 2-methyl -4-thioaryl-6-acetamido-s-triazines.A scheme was proposed for the formation of substituted s-triazines by the successive transformation of the intermediate radicals.Translated from Izvestiya Akademii Nauk SSSR, Seriya Khimicheskaya, No. 11, pp. 2591–2593, November, 1982. 相似文献

Photochemical reactions involving kynurenines, viz., molecules present in the eye lens, can result in modifications of the lens proteins and cause a development of a cataract.
The rate constants of the reactions of photoexcited kynurenine with several amino acids and antioxidants contained in the
lens were measured. The most efficient quenchers of triplet kynurenine are amino acids tryptophan and tyrosine, as well as
antioxidant ascorbate. In all cases, the quenching reaction proceeds by the electron transfer mechanism, except for the reaction
with oxygen where transfer of the triplet energy to the oxygen molecule occurs.

The photoprocesses in substituted 4-dicyanomethylene-4H-pyran (DCM) derivatives were studied theoretically and experimentally. The experimental spectral and luminescent parameters of the molecules under study are in good agreement with the results of quantum-chemical calculations. Trends changes in the spectral and luminescent properties depending on the molecular structure were established. The appearance of the S2 level near the S1 level in the scheme of the energy states of symmetrically substituted DCM (bis-DCM) causes changes in photophysical processes and a drop in the fluorescence quantum yield. 相似文献

The spectral and luminescent properties of acridine in SiO2 films synthesized by the sol-gel method using acid hydrolysis of tetraethoxysilane are studied. It is shown that acridine in films exists in protonated form. Ammonia-gas-sensing properties of films doped with acridine are studied by the fluorescence response (decrease in the intensity) of the protonated form. The possibility of multiple use of a sample without a noticeable decrease in its sensitivity is demonstrated. It is shown that the fluorescence response to a maximal permissible concentration of ammonia in the gas mixture with argon is 6–8%. 相似文献

Spectral and luminescent properties of mixed-ligand Eu(III) complexes were studied in solutions and in polyvinylcarbazole (PVC) thin films. Trends in their variations were found depending on the complex structure and excitation mode. The electroluminescence was observed in ITO/PEDOT/Eu complex:PVC/CaMg/Al devices. Their current-voltage and voltage-brightness characteristics were investigated. 相似文献

Organic thin-film structures based on Eu(III), Tb(III), and polyvinylcarbazole coordination compounds are synthesized. Their
photo- and electroluminescent properties and volt-ampere and volt-brightness characteristics are investigated. 相似文献
