One of the important directions in modern mathematics is applications of Poisson structures and to various problems of mathematics and theoretical mechanics. These problems arise in dynamics of a rigid body, the celestial ...

Results of a theoretical study of the molecular structure of arglabin are pesented. Quantum chemical calculations of the geometry and physicochemical characteristics of arglabin are performed by the semi-empirical РМ6 ...

At the last years interest to energetically influence on material for the reason change their characteristic remains stabiles high. With calculation of the individual particularities material and with using influence choices ...

Dynamic and static quenching of fluorescence occurs upon contact interaction of oxygen molecules. Of the simplest models of the complex of oxygen and anthracene, a complex consisting of one molecule of oxygen and anthracene ...

For a theoretical interpretation of the fast intermolecular proton exchange (IPE) reaction mechanism by ab initio methods of modern quantum chemistry potential energy surface in the oxymethyl – ammonia acid-base free-radical ...

Cyclic dimers of aminoacetic acid were investigated by ab initio UHF 3–21G method using the Gaussian-2009 program. Four types of aminoacetic acid cyclic dimers were registered by quantum-chemical method. Comparative ...

Studies of structural and phase state of Be-Fe-Be three-layer system were conducted using Mössbauer spectroscopy method at 57Fe nuclei after krypton ions irradiation with energy of 280 keV and subsequent isochronous ...
