Surface vibrational spectroscopy has developed rapidly over the past decades, thanks to the
advent of ultrashort tunable laser pulses in the mid-infrared range. In particular, femtosecond …

It has long been debated whether the results of classical surface science investigations
carried out under ultrahigh vacuum (UHV) can be truly transferred to heterogeneous …

There is a long-standing question whether results of studies of surface processes under
ultrahigh vacuum (UHV) can be truly transferred to the conditions of heterogeneous …

Femtosecond broadband sum frequency generation (SFG) spectroscopy is applied to
surface studies of the archetypical non-centrosymmetric semiconductor GaAs (001) …

A generalized theory of frequency-and time-resolved vibrational sum-frequency generation
(SFG) spectroscopy of adsorbates at surfaces is presented using the density matrix …

CO on Ru 101 0 was investigated by broadband femtosecond sum-frequency spectroscopy
at 200 K. Approximately half of the frequency shift of 71 cm 1 over the coverage range from …

Hot electrons created by femtosecond laser pulses can transiently increase the occupation
of the antibonding 2π* orbital of a diatomic adsorbate and change its bonding configuration …

We present a set of experiments that provide a complete mapping of coherent and
incoherent vibrational relaxation times for a molecule on a metal surface, CO∕ Ir {111}⁠ …

The first measurement of the vibrational hot band of the C–O stretch of carbon monoxide
adsorbed on Ir {111} has been obtained by sum frequency generation (SFG) with intense …

We have studied the coverage-dependent energy transfer dynamics between hot electrons
and CO on Cu (110) with femtosecond visible pump, sum frequency probe spectroscopy. We …
