INTERMOLECULAR POTENTIAL ENERGY SURFACES FOR THE Rg-SH ( ) COMPLEXES (Rg:Ne,Kr) STUDIED BY FTMW SPECTROSCOPY

چکیده
%$& in the 5 17 GHz region for Kr-SH, respectively. In these spectra ' -type doublings and hyperfine splittings associated with the H nuclei have been observed. Although the spectral pattern of Kr-SH is relatively regular, that of Ne-SH is fairly irregular with the dependence of the ' -type doubling very different from other Rg-SH or Rg-OH species. In the present analysis, we used a program system explicitly taking into account of the large amplitude stretching and bending motions coupled with the fine and hyperfine structure. We were able to determine intermolecular potential energy surfaces(IPS) for both of the species. We have obtained systematic information on the intermolecular interaction, and compared it with that of Ar-SH. The average potential turned out to be fairly shallow and isotropic, especially for Ne-SH, and this may be the source of the irregular spectral pattern of Ne-SH.

An inversion procedure is used to obtain from the extended principle of corresponding - states the pair interaction potentials for argon, krypton and its mixture over a tetnperature range from absolute zero to the onset of ionization. The experimentally-reduced viscosity collision integrals obtained from the corresponding - states correlation have been inverted directly to give the reduced...

An overview on potential energy surfaces of rare-gas dihalogen van der Waals clusters
In this review we report on interaction potential surface calculations of Rg–XY (Rg = rare gas and X, Y = halogens) van der Waals (vdW) complexes. Experimental data available on the structure and dynamics of such systems mainly originate from the B← X excitation spectroscopy and, therefore, potential surfaces for both electronic states involved are required for the theoretical treatments. Hence...

The understanding of the intermolecular pair potential is important for determining the physical andchemical properties of the matter. The new data for noble gasses was calculated with Soft-CoreDouble Yukawa Potential (SCDY). We studied the effect of the Soft- Core potential on the phasebehavior with Hartree-Fock-Dispersion (HFD) Potential. This model had a steep repulsionexponential term and d...
