Ortho-H2 molecules in the j = 1 state are predicted, on the basis of a simple extension of the distorted wave approximation, to excite shear horizontal (SH) polarized surface phonon modes, which are symmetry forbidden in inelastic He atom planar scattering. The symmetry breaking is provided by rotational flip transitions which couple efficiently to the shear horizontal modes. A confirmation is provided by the observation of SH surface phonons in phonon inelastic scattering of o-H2 from NaCl(001)
