    Computer study of the absorption of ethane by aqueous ultradispersed medium: IR spectra [Текст] / A. N. Novruzov, O. R. Rakhmanova, A. E. Galashev // Colloid Journal (Translation of Kolloidnyi Zhurnal). - 2008. - Vol. 70, № 1. - С. 55-63

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.

IR ABSORPTION
Аннотация: The method of molecular dynamics along with the flexible model of molecules are used to study the spectral characteristics of systems of clusters of (H2O) n , (O2) m (H2O) n , and (O) i (H2O) n , m меньше либо равно 2, i меньше либо равно 4, 10 меньше либо равно n меньше либо равно 50. It is demonstrated that the integral intensity of absorption of IR radiation decays after water clusters adsorb oxygen. In addition, the adsorption of oxygen causes a significant decrease in the reflection coefficient R of monochromatic IR radiation. In so doing, the R(?) spectrum splits into bands and exhibits seven peaks in the frequency region of 0 меньше либо равно омега меньше либо равно 3500 cm в степени -1. The dissociation of oxygen molecules captured by clusters makes the peaks of R(омега) spectrum more resolved. The attachment of molecular oxygen by clusters leads to decay of the power of their IR radiation, while the capture of atomic oxygen, on the contrary, is accompanied by an increase in the rate of dissipation of energy accumulated by water aggregates.

IR SPECTRA
Аннотация: Spectral characteristics of (H2O) i , N2(H2O) i , and (N2)2(H2O) i cluster systems, where 10 меньше либо равно i меньше либо равно 50, are studied in the 0 меньше либо равно эпсилон меньше либо равно 3500 cm в степени -1 frequency range with the molecular dynamics method on the basis of a flexible molecule model. After nitrogen is captured by an aqueous disperse system, the absorption of the IR radiation by this system increases owing to the enhancement of intramolecular vibrations. In general, the reflection of the outer IR radiation by nitrated aqueous disperse systems is attenuated; however, when the nitrogen concentration increases twofold, there is a tendency toward an increase in the fraction of reflected radiation. As the nitrogen concentration in a system of water clusters rises, the power of radiation emitted by the system increases significantly and the number of electrons interacting with the outer IR radiation decreases.

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.

DIELECTRIC CONSTANT
Аннотация: Absorption of oxygen molecules by water clusters with sizes of 10 меньше либо равно i меньше либо равно 50 is studied by the molecular dynamics method using the modified TIP4P model. It is revealed that the total dipole moment of the clusters nonmonotonically increases with their sizes. Absorption of O2 molecules tends to raise the static permittivity of the ultradispersed medium formed by the clusters. The real and imaginary parts of the permittivity of water clusters with absorbed O2 molecules are aperiodic functions of frequency. The permittivity components turn out to be nonmonotonic functions of cluster sizes. The IR absorption and reflectance spectra are calculated for clusters of pure water and aggregates with absorbed O2 molecules. After the addition of oxygen molecules, the absorption coefficient of the clusters decreases, while the reflection coefficient increases. It is concluded that the capture of oxygen molecules by atmospheric moisture may reduce the greenhouse effect.

WATER CLUSTERS
Аннотация: The stability of water clusters containing nitrogen oxide molecules is studied by the molecular dynamics method. The composition and size of thermodynamically stable heteroclusters are determined. The inclusion of two molecules of nitrogen oxide into aggregates containing seven or more water molecule increases the cluster stability. The correlation between the stability of heteroclusters and the ratio of self-diffusion coefficients of molecules of different kinds is observed. The real part of the cluster permittivity is maximal in the vicinity of the frequency of 200 cm–1. The inclusion of nitrogen oxide molecules into water clusters increases the characteristic frequency of dielectric relaxation. In general, heteroclusters are more stable with respect to perturbations caused by an external electric field than pure clusters with the same number of water molecules. The clusterization of water vapors accompanied by absorption of polar molecules of impurity favors a decrease in the greenhouse effect.

SOLID METALS
Аннотация: Arc current fluctuations between a solid metal electrode and a liquid melt of alkaline carbonates at atmospheric pressure are measured. Arc current fluctuation power spectra are determined from the measurement data. It is shown that the fluctuation power is inversely proportional to the frequency (1/f-fluctuations). The fluctuations have a normal Gaussian distribution. The observed 1/f fluctuations exhibit scale invariance.

BOILING-UP LIQUID -- CRITICAL MODES -- VAPOR FORMATION
Аннотация: Change of the shape of a boiling-up liquid jet flowing from a high-pressure vessel at high superheatings was investigated experimentally. Mechanisms of volumetric heterogeneous and homogeneous nucleation are distinguished and their connection with critical modes of outflow is determined. Results of the experimental study of recoil of boiling-up liquid jets in a thermodynamically strong nonequilibrium mode of outflow are presented. The dynamics of vapor content fluctuations is studied by a method of photometry of passed laser radiation. Fluctuations of pressure in a superheated liquid jet at various mechanisms of vapor formation are measured by a method of strain metering. It was found that in intense volumetric boiling-up of a superheated liquid jet the power spectrum of fluctuations has a low-frequency component (flicker-noise) which diverges according to the 1/f law. This effect is related to nonequilibrium phase transitions in the system
