Paramagnetic Susceptibility of a $2p$ Unpaired Electron in a Crystalline Field

Paramagnetic susceptibility of the cubic crystal $\mathrm{O}_2^{}{}_{}{}^{+}$ ${\left(\mathrm{A}\mathrm{s}{}_{}{}^{\mathrm{V}}{}_{}{}^{}\mathrm{F}_6^{}{}_{}{}^{}\right)}^{-}$ between 4.2 and 300°K reveals a complete quenching of the orbital moment of the $2{p_{\mathrm{I}}}^{4}2{p_{\mathrm{II}}}^3$ configuration of the $\mathrm{O}_2^{}{}_{}{}^{+}$ molecular cation. No ordering of the $\mathrm{O}_2^{}{}_{}{}^{+}$ molecular cations has been detected in the range of measured temperature because of the large interatomic distance $\mathrm{O}_2^{}{}_{}{}^{+}$-$\mathrm{O}_2^{}{}_{}{}^{+}$ of 4.00 Å.
