energy levels are flipped @tetrahedral ligands configuration relative to @octahedral case
High spin system example [Fe(H${}_2$O)${}_6$]${}^{3+}$ ... d${}^5$ system = t${}_{2g}^3$ e${}_g^2$ Crystal Field Splitting Energy = 0 Weak field ligands
Low spin system example [Fe(CN)${}_6$]${}^{3+}$ ... d${}^5$ system Strong Field #Energy Gap > Pairing Energy
"Transition Complex" "cofactor"
paired -> diamagnetic, unpaired -> paramagnetic
