Ground state rotational constants were determined for 14 isotopologues of o-xylene. These rotational constants have been corrected with the rovibrational constants calculated from a quantum chemical force field. It was found that the derived semiexperimental equilibrium rotational constants of the ...

Structure of p-xylene from its P.M.R. spectrum in the nematic phase 来自 Taylor & Francis 喜欢 0 阅读量: 7 作者:Daniel,Canet,&,Jean,Barriol 摘要: The GDIM hamiltonian is a general expression for partitioning the polyatomic hamiltonian into atomic and diatomic fragments. The partitioning is ...
A typical method of preparation is to dissolve <0.01% PE in xylene at a temperature of 135–138°C and then cool slowly to 70–80°C. The small PE crystals that precipitate are several microns across and only 10–20 nm thick. The thickness of these platey crystals (lamellae) is ...
Structure of p -xylene from its P.M.R. spectrum in the nematic phasedoi:10.1080/00268977400101461The GDIM hamiltonian is a general expression for partitioning the polyatomic hamiltonian into atomic and diatomic fragments. The partitioning is determined by a set of arbitrary functions of nuclear ...
Inorganic–organic hybrid materials: synthesis and crystal structure determination from powder diffraction data of Pb 2(O 3PCH 2C 6H 4CH 2PO 3) A new lead diphosphonate, Pb 2(O 3PCH 2C 6H 4CH 2PO 3) was hydrothermally synthesized from tetraethyl α, α′- p-xylenediphos-phonate and Pb...
Computer simulation of the structure, energetics and diffusion properties of para-xylene in zeolite Na-Y The properties of para-xylene adsorbed in zeolite Na-Y were studied by molecular simulations. Constrained reaction coordinate minimizations were used to calculate the minimum energy path for the di...

carrier materials. As catalysts, they may contain metal in the pore. Applications of zeolites as supports, solid acids, orshape selective catalysisare common.Zeolitesare widely used in refining andpetrochemicals, e.g., ultrastabilized Y zeolite forfluid catalytic crackingand ZSM-5 for xylene...
Reactions were quenched by the addition of 2 Â RNA loading buffer (90% formamide, 25 mM EDTA, 0.02% xylene cyanol and 0.02% bromophenol blue) and samples were analysed using 20% Urea-TBE PAGE, stained with RedSafe dye and imaged via a GE Healthcare Typhoon Variable Mode Imager. Direct...
