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 WebNov 10, 2014 · "Smearing" is not well-defined enough for that. 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.
