      abstract     = {We use a pump-probe scheme to measure the time evolution of
                      the C K-edge x-ray absorption spectrum from CO/Ru(0001)
                      after excitation by an ultrashort high-intensity optical
                      laser pulse. Because of the short duration of the x-ray
                      probe pulse and precise control of the pulse delay, the
                      excitation-induced dynamics during the first picosecond
                      after the pump can be resolved with unprecedented time
                      resolution. By comparing with density functional theory
                      spectrum calculations, we find high excitation of the
                      internal stretch and frustrated rotation modes occurring
                      within 200 fs of laser excitation, as well as thermalization
                      of the system in the picosecond regime. The ∼100  fs
                      initial excitation of these CO vibrational modes is not
                      readily rationalized by traditional theories of nonadiabatic
                      coupling of adsorbates to metal surfaces, e.g., electronic
                      frictions based on first order electron-phonon coupling or
                      transient population of adsorbate resonances. We suggest
                      that coupling of the adsorbate to nonthermalized
                      electron-hole pairs is responsible for the ultrafast initial
                      excitation of the modes.},
