Multireference Character for 4D Transition Metal-Containing Molecules

Description: This article proposes new criteria, namely T₁ ≥ 0.045, D₁ ≥ 0.120, and %TAE ≥ 10%, as a gauge for 4d transition metal-containing molecules to predic the possible need to employ multireference (MR) wave function-based methods to describe energetic and spectroscopic properties.
