title: The spin population difference of hydrogen atoms dissociated from mercury hydride molecules.
abstract: The spin population difference between m(s) = 1/2 and - 1/2, (malpha - mbeta)(t) of the hydrogen atoms dissociated from the mercury hydride molecules is calculated as a function of time for the reaction of Hg* + H2 in a magnetic field. Starting from zero value, the population difference increases to a certain limit that is equal to the room temperature population difference. The H/D electron spin resonance (ESR) signal ratio obtained from the isotopic experiment, Hg* + H2/D2, is also explained by comparing the ratio of (malpha - mbeta)H(t) and (malpha - mbeta)D(t). The isotopic effect is interpreted to originate mostly from spin-rotation constant energies of mercury hydride molecules.
