The magnetic susceptibility of oxygen in a clathrate compound. II

It is shown that previous measurements on the magnetic susceptibility of oxygen in a clathrate compound can be explained if it is assumed that the molecule, instead of being completely free as previously assumed, is subject to a potential V$_{0}$(1 - cos 2$\theta $) with V$_{0}$/k = 32 degrees K. $\theta $ is the angle between the figure axis of the molecule and the c axis of the crystal. The susceptibility measurements were extended down to 0$\cdot $25 degrees K and showed good agreement with the theory.
