Abstract : The electric susceptibility contribution to Verdet's constant of atomic hydrogen V(e) is derived for Zeeman splittings that are much smaller than the fine structure splitting but greater than the hyperfine splitting. Neglect of the electron spin in this calculation would result in a value for V(e) which is 18.2% low. The contribution to V(e) from continuous states is 6.8% of the contribution from the descrete states, at a wavelength of 6000A. The total Verdet constant at 6000A, including the magnetic susceptibility contribution, for 2.69 x 10 to the 19th power atoms per cu. cm is 10.8 micro-min. per cm per oersted. The experimental value of Verdet's constant of molecular hydrogen under these conditions is 5.82 micro-min. per cm per oersted. This difference in Verdet's constant between atomic and molecular hydrogen can be used to determine the atomic concentration in a mixture. (Author)
