Fig. 7: Computed Zn-specific descriptor correlations with experimental R-VtC-XES gap.

Linear correlation fits for calculated descriptors against experimental R-VtC-XES energy gap (E(gap,exp)): a zinc-specific hardness (ηZn) versus E(gap,exp); b zinc-specific absolute electronegativity (χZn) versus E(gap,exp); c zinc-specific global electrophilicity index (ωZn) versus E(gap,exp) and d E(OMO,Zn p) versus E(gap,exp).
