These calculations demonstrate that the contributions from s orbitals are negligible for the spin susceptibility tensors and exactly zero for the orbital susceptibility. The contributions from p orbitals are also very small. The full response stems nearly completely from the d orbitals. Scanning the ...
1e. Oxygen vacancies affect the electron occupancy (donate electrons to Ni-site eg orbitals) and electron-electron correlation energy and band gap in SNO, which modulates the MIT behavior. S-SNOM images provide a direct and facile way to monitor these modulations. Hydrogen dopants provide another...

In the diol epoxide of benzo[a]pyrene all five of the uppermost π orbitals are destabilized compared to those in pyrene. This destabilization, which in the second highest occupied π orbital has a magnitude greater than 0.4 eV, is expected to aid in the stabilization of intermediates ...
orbitals of the three neighbour nitrogen atoms give rise to a set of non-degenerate A and degenerate E single particle defect states. The six defect states are occupied with 10 electrons in the negative charge state. Depending whether the in-plane dangling forms the defect state bonds or the ...
The valence s orbital of the main group elements is always below the p valence orbitals, but the valence s orbital of the transition metals is above the valence d orbitals. The energetically lower lying valence orbital concentrates in bonds toward the more electropositive methyl substituents ...
首先我们要假设卡宾碳原子是sp2杂化的,三个杂化轨道中的两个会和氢原子成键,形成两个成键轨道和两个反键轨道,有一个杂化轨道没有用上,是非键轨道,而碳原子自己还有一个p轨道垂直于CH2平面,并且没有被用上,是完全的非键轨道。 这里需要说一下电子如何在两个轨道之间分布的问题,这也涉及到了Hunt's rule的本质...
In contrast to the knowledge that the excellent ORR activity of Pt catalyst is caused by its partially filled d orbital, our first-principle calculations suggest that the strong charge exchange between Pd-4d and Pb-(sp) orbitals on the Pd3Pb TPs {110} facet results in a Pd-Pb local ...
The photoelectron branching ratios and the partial oscillator strengths (cross sections) for photoionisation of the valence orbitals of N 2O and CO 2 have been obtained in the energy range 20–60 eV using the magic angle dipole (e, 2e) m... CE Brion,KH Tan - 《Chemical Physics》 被引...
the standardG0W0approach underestimates the band gap by approximately 220 meV. The maximally localized Wannier functions obtained from the Wannier90 packages46,47were used to plot theGWquasiparticle band structure (Fig.1e). In the construction of the Wannier functions, thesandporbitals of both ...
