Values of 103 Vt for H2O and D2O. Columns A and A′ are measured values of the Verdet constants, under constant pressure conditions, reduced to V20°=0.01309 min per-oer-cm as the accepted value for H2O at 5893 A. Columns B and B′ are Verdet values calculated for constant volume conditions by dividing by density.

Comparison of the Faraday dispersion for NO gas with Serber’s theory. Values of r=Vobs/Vcalc. The two-term paramagnetic form has chosen resonant frequencies corresponding to the two dissociation energies of the molecule. The single-term paramagnetic form has a resonant frequency chosen to give the best fit. The diamagnetic single term is shown as a curiosity with the resonant frequency chosen to correspond to the ionization energy of the molecule.
