    "abstract": "The role of vibrational excitation of a single mode in the scattering of\nmethane is studied by wave packet simulations of oriented CH4 and CD4 molecules\nfrom a flat surface. All nine internal vibrations are included. In the\ntranslational energy range from 32 up to 128 kJ/mol we find that initial\nvibrational excitations enhance the transfer of translational energy towards\nvibrational energy and increase the accessibility of the entrance channel for\ndissociation. Our simulations predict that initial vibrational excitations of\nthe asymmetrical stretch (nu_3) and especially the symmetrical stretch (nu_1)\nmodes will give the highest enhancement of the dissociation probability of\nmethane.",
