    A computer study of the absorption of infrared radiation by systems of molecular clusters [Текст] / A. N. Novruzov, V. N. Chukanov, O. R. Rakhmanova, A. E. Galashev // High Temperature. - 2006. - Vol. 44, № 6. - С. 932-940

MOLECULAR CLASTERS
Аннотация: The method of molecular dynamics is used to investigate the process of absorption of N2O and CH4 molecules by water clusters and to determine the frequency spectra of permittivity for systems consisting of clusters mixed in different ratios, namely, (H2O)n, (N2O)i(H2O)10, and (CH4)i(H2O)10. IR-radiation absorption spectra for these systems are calculated and analyzed; the radiation power scattered by these systems and the tangent of dielectric loss angle are determined. The inclusion of anharmonicity of phonon oscillation makes it possible to explain the origin of characteristic frequencies appearing in IR spectra of mixtures of cluster systems. The capture of molecules of greenhouse gases by an ultradisperse aqueous medium affects the ability of this medium to absorb terrestrial radiation, i.e., reduces the greenhouse effect.

FLEXIBLE MOLECULES -- IR SPECTRUM -- MOLECULAR DYNAMICS
Аннотация: Abstract-Interaction of bromine ions with water clusters that have absorbed the molecules of oxygen and ozone is studied using a molecular-dynamics simulation of flexible molecules. The cases of location of Br-ions on the surface and in the bulk of the cluster are described. Water clusters with ozone molecules remain stable during their interaction with the Br - ions, while oxygen molecules are found to evaporate from the cluster when Br - ions appear in its bulk. In the presence of Br - ions, the infrared spectra of systems with O 3 molecules are observed to be intensified. The intensities of the IR spectra with O 2 molecules may both increase and decrease depending on the arrangement of the Br - ions. The Raman spectra are sensitive to the appearance of Br - ions only for systems that contain oxygen molecules. As a result of interaction with the Br-ions, the power of IR radiation emitted by the clusters can not only increase, but also decrease

BROMINE IONS -- INFRARED AND RAMAN SPECTRA -- WATER CLUSTERS
Аннотация: The interaction of (Br -) iH 2O) 50-i, 0 ≤ i ≤ 6 clusters with oxygen and ozone molecules is investigated by the method of molecular dynamics simulation. The ozone molecules as well as the bromine ions do not leave the cluster during the calculation of 25 ps. The ability of the cluster containing molecular oxygen to absorb the infrared (IR) radiation is reduced in the frequency range of 0 ≤ ω ≤ 3500 cm -1 when the number of the bromine ions in the cluster grows. The intensity of the Raman spectrum is not changed significantly when the Br - ions are added to the ozone-containing system. The power of the emitted IR radiation is increased when the number of bromine ions grows in the oxygen-containing system. The data obtained in this study on the IR and the Raman spectra of the water clusters that contain ozone, oxygen, and Br - can be used to develop an investigation of the mechanisms of ozone depletion

DIELECTRIC PERMITTIVITIES -- FREQUENCY DEPENDENCE -- HIGH-FREQUENCY MODE
Аннотация: Methane adsorption by water clusters including 50 molecules was studied by the molecular dynamics (MD) technique. The calculated frequency dependence of the real and imaginary parts of the dielectric permittivity points to the prevalence of a high-frequency mode in the spectra of these parameters after methane is adsorbed by water clusters. Such changes are also observed in the spectrum of the IR radiation absorption coefficient; however, the average value of this coefficient remains nearly the same. Methane adsorption causes a considerable increase in the reflection coefficient of the disperse water medium and the integrated power of IR radiation emission

IR SPECTRA
Аннотация: Absorption of ethane molecules by water clusters containing 10–20 molecules is studied by the molecular dynamics method. The (H2O) n (I), C2H6(H2O) n (II), and (C2H6)2(H2O) n (III) cluster systems are composed on the basis of specific statistical weights. Spectral characteristics of system and single clusters are determined in the frequency range of 0 меньше либо равно омега меньше либо равно 1000 cm в степени -1. In this frequency range, both real and imaginary parts of dielectric permittivity decrease monotonically after the absorption of C2H6 molecules by an aqueous ultradispersed system. Integral coefficient of IR absorption increases, while average (over frequency) reflection coefficient decreases after the absorption of ethane molecules. The intensity of IR scattering by the systems of clusters containing C2H6 molecules lowers. Maximal values of radiation power for water clusters with various sizes are balanced with the capture of ethane molecules by the clusters, whereas oscillations in the size dependence of the density of electrons that are active with respect to IR radiation decrease.
