Intra- and Intermolecular Electrial Effects on Nuclear Magnetic Resonance, Nuclear Quadrupole Resonathe effects of these interactions on molecular properties are accurately determined by properties which can be calculated by analytical differentiation at the SCF level with Derivative Hartree-Fock (DHF) theory. Several applications of this model are compared with experiment.作者: OVERT 時(shí)間: 2025-3-22 18:28
The IGLO method. Recent developmentswith MC-IGLO are presented, e.g. on the dependence of chemical shifts on geometry, on idealized annulenes and the limits of the Spiesecke-Schneider relation, on the heavy-atom effect, the shielding along the potential curve of He., and generally on a comparision of MC-IGLO with SCF-IGLO.作者: palliative-care 時(shí)間: 2025-3-23 00:22
Electronic Current Density Induced by Magnetic Fields and Magnetic Moments in Molecules evaluated via approximate coupled Hartree-Fock perturbation theory. Shubnikov theory of magnetic groups has been examined in Sec. 3 to predict the essential features of the current density vector field. The results of large basis set calculations on benzene and borazine are reported in Sec. 4.作者: 不能平靜 時(shí)間: 2025-3-23 03:03
Electronic Mechanisms of Metal Chemical Shifts from Ab Initio Theoryexes, and p-excitation mechanism for s.p. metal complexes. Though the paramagnetic term is the origin for most complexes, the chemical shifts of the Ga and In (s.p.) halides are primarily determined by the diamagnetic term, and therefore by the structural factors (geometry and nuclear charges) alone.作者: Glaci冰 時(shí)間: 2025-3-23 08:13 作者: 補(bǔ)助 時(shí)間: 2025-3-23 10:53 作者: dissent 時(shí)間: 2025-3-23 14:47
