Abstract
Perturbation theory calculations of the rotational motion of a hydrogen molecule rotates at the center of a p-type unit cell are reported. These calculations show that the molecular axis of H-2 is azimuthally delocalized and hence it can be tunneled into classical forbidden region where the structures are indeed "c" type rather than "p" type. Thus estimating the quantum effects of those species will change the monolayer configurations into c-type structures and hence match the recently reported Helium Atom Scattering (HAS) results.
