Determination and Recovery of Spin‐States for a High‐Spin and a Spin‐Crossover Complex by Means of X‐Ray Wavefunction Refinement

open access: yesChemistry – A European Journal, EarlyView.
The determination of spin‐states by methods like Hirshfeld atom refinement is a promising development in the field of quantum crystallography. To this end, we present x‐ray wavefunction refinement as a next step in this process, identifying the spin and translating it into a physical wavefunction.
