Abstract

We investigate the molecular orientation dependence of the (o)rtho-(p)ara H2 conversion on Fe(OH)3 cluster. Taking Fermi's contact interaction as perturbation, we find that the o-p H2 conversion yield for the molecular orientation angle θ= 10° with respect to the surface normal is larger than that for θ= 70°.
