Orbital occupancy use smearing
WebIn the case for $\ce{PdO}$I get a set of occupied orbitals ($13a_1$, $7b_1$, $6b_2$, $2a_2$), whereby two are singly occupied. To get my desired active space of ($4a_1$, $2b_1$, $2b_2$, $1a_2$), I would simply have to close orbitals according to ($9a_1$, $5b_1$, $4b_2$, $1a_2$). Is this a sensible approach? software quantum-chemistry molpro casscf http://muchong.com/t-1860442-1

WebFeb 11, 2024 · To study the effect of e g occupancy lower than 1 on the peroxidase-like activity of perovskites, we investigated three Mn-based perovskites with the e g occupancy of Mn varying from 0.68 to ~0.08 ... WebJun 3, 2024 · Low spin: CFSE = ( − 4)(2 5)ΔO + P = − 8 5ΔO + P, where P is the pairing energy. Energy difference = -ΔO + P. The pairing energy P is the energy penalty for putting two electrons in the same orbital, resulting from the electrostatic repulsion between electrons. For 3d elements, a typical value of P is about 15,000 cm -1.

WebAug 21, 2024 · This tells QUICKSTEP to use a smearing function for the electron occupation. In this example, we use the Fermi-Dirac smearing function, with the electron temperature being set to 300 K. Note that, in CP2K, one can explicitly define the unit of a given input value by using a unit enclosed in square bracket, such as “[K]”, before the value.
