As the accuracy of our measurements increased, zero point vibrational and centrifugal effects became important, so I wrote this paper concerning their effects on the spin–spin magnetic interaction, the spin-rotational magnetic interaction, the rotational magnetic moment, the magnetic shielding of the nucleus and the molecular diamagnetic susceptibility. Although the general results apply to any molecule, the detailed discussions are limited to 1Σ diatomic molecules and specifically to H2, D2 and HD. I showed, for example, that the ratio of the rotational magnetic moments of H2 and D2 should be slightly different from the ratio of the masses. The theory also provides important corrections in determining the average value of 〈1/R3〉, which is needed to calculate the magnetic portion of the tensor interaction to see if there is a nonmagnetic tensor interaction between two protons, as discussed in Paper 6.3.
