Oxygen magnetic susceptibility

The presence of a few atomic percent of oxygen in tantalum increases electrical resistivity, hardness, tensile strength, and modulus of elasticity, but decreases elongation and reduction of area, magnetic susceptibility, and corrosion resistance to HF . 

The quadrupole effects mentioned in Section I.B.(l) apparently are small, as magnetic susceptibility measurements18 have revealed that the energy differences between different orientations of an oxygen molecule in a /3-hydroquinone cavity become only noticeable at liquid helium temperatures.

The Pu and Am" " ions have a 5 f and 5 f well localized f-shell this is borne out clearly by the fact that their magnetic susceptibility is well explained in the atomic picture (see Chap. D). Nevertheless, this f-configuration is non-localized in metals, therefore, it might well be assumed to form some amount of covalent bonding by hybridization with the 2p electrons of the oxygen ion (see later, and Chap. E). 

V(urea)6]I3 crystallizes from a solution of the sulfate on adding potassium iodide. The oxygen atoms of the urea molecules form an octahedron twisted T about the three-fold axis with V—O lengths of 1.98 A.286 The magnetic susceptibility of the iodide and perchlorate salts... 

MAGNETIC SUSCEPTIBILITY. Pinnick (58) has correlated the magnetic susceptibility of synthetic graphite with the a-dimension of the lattice plane. There is a sharp increase in susceptibility as a grows from 50 to 150 A., and the susceptibility remains constant thereafter to 1000 A. Juza (39) has shown that the adsorption of oxygen on charcoal at room temperature is molecular, as magnetic susceptibility does not change.
