Abstract
The ortho-para conversion rate of hydrogen molecules physisorbed on transit
ion metal oxides is shown to be drastically enhanced for selected values of
the parameters. This new electron-nucleus resonant mechanism is suggested
to interpret the observed accelerations of the conversion rate by an extern
al magnetic field. The sensitivity of the magnetic field acceleration upon
catalyst pretreatments might have important practical applications in the s
election and preparation of industrial catalysts.
