Orbital occupancy use smearing
http://muchong.com/t-1860442-1 WebOrbital occupancy. Although HF orbitals are, by definition, the best possible for a singleconfiguration wavefunction, it is actually possible to find a better set of orbitals, called natural orbitals ,31 to describe the correlated p (r). The natural orbitals are maximum-occupancy orbitals, determined from itself and guaranteed to give fastest ...

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
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. Webuse smearing和occupation thermal是同一个问题，没有区别。 DIIS的话，需要看一些相关文献才能有个大概的了解，简而言之，是使用前一循环中的部分波函数/电子密度作为后一 …

If it just refers to wave functions spread out in space, then the double-slit experiment is enough to find something similar. Or a simple electron orbital in an atom. Sicktoaster said: Smearing you think of it smearing out to cover a wider area, which it does not appear to do.
