contents The vibrational relaxation of NO molecules scattering from an Au(111) surface has served as the focus of efforts to understand nonadiabatic energy transfer at metal-molecule interfaces. Experimental measurements and previous theoretical efforts suggest that multi-quantal NO vibrational energy relaxation occurs via electron hole pair excitations in the metal. Here, using a Linearized Semiclassical approach, we accurately predict the vibrational relaxation of NO from $ν_i=3$ state for different incident translational energies. We also accurately capture the central role of transient electron transfer from the metal to the molecule in mediating vibrational relaxation process, but fall short of quantitatively predicting the full extent of multi-quantum relaxation for high incident vibrational excitations ($ν_i = 16$).
