Second-order M ja:math ller–Plesset, perturbation theory geometry optimizations for AlH 4 , SiH 4 , PH 3 , H 2 S and HCl are performed with [11s8p2d1f] and [11s8p3d2flg] basis sets of contracted Gaussian-type functions. The electric dipole, quadrupole and octopole moments of these ...
Based on the structure, as determined by microwave spectroscopy30and subsequently supported by ab initio calculations33, the H2S dimer is known to be hydrogen bonded. However, its hydrogen-bonded geometry shows differences from that of the H2O dimer, which can be understood by considering the monom...

[39]. They concluded from their best low-energy electron diffraction analysis that the top-layer Zn ion is displaced downward by Δd(Zn) = − 0.045 ± 0.01 nm and likewise the top-layer oxygen by Δd(O) = − 0.005 ± 0.01 nm, leading to a 12° ± 5° tilt of the Zn-O ...
The adsorption of hydrogen, ethylene, acetylene, cyclohexane and benzene was studied on both the (111) and stepped [6(111) × (100)] crystal surfaces of iridium. The techniques used were low energy electron diffraction, Auger electron sp... B.E,Nieuwenhuys,and,... - 《Surface Science》...
We suspect that this interaction is very sensitive to the orientation of the two lone electron pairs on the sulfur atom relative to the π electron cloud of the aromatic ring, so that interaction configurations that provide significant bonding energy exist only within a narrow configurational space....
The solution containing the dispersed precursor was subjected to microwave irradiation for ∼5 min, and the organic solvent was subsequently removed via centrifugation.
