Semiclassical second order vibrational perturbation theory for hopping rates of H and D atoms on Pt(111) and H on Ru(0001).

Wolynes's theory for tunneling in dissipative systems was constructed for parabolic barriers. Its recent generalization to anharmonic potentials is further developed, most notably by employing the second order vibrational perturbation theory expressi…
