TLDR
In this article, the absorption spectra of the ferrate (VI) ion (FeO2-4) in K2MO4 (M = S, Se, Cr, Mo) host lattices consist of a series of relatively weak bands at low energy, which can be assigned to transitions within the partially filled 3d shell and some intense bands at higher energy.About:

Automated Construction of Molecular Active Spaces from Atomic Valence Orbitals
TL;DR: The atomic valence active space technique is introduced, a simple and well-defined automated technique for constructing active orbital spaces for use in multiconfiguration and multireference electronic structure calculations that makes MR calculations easier to execute, easier to reproduce by any user, and simplifies the determination of the appropriate size of the active space required for accurate results.
