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 …

Abstract Infrared (IR)-visible (Vis) sum frequency generation (SFG) is a second-order
nonlinear optical process which is forbidden in centrosymmetric bulk media or isotropic …

The lack of understanding of the temporal effects and the restricted ability to control
experimental conditions in order to obtain intrinsic spectral lineshapes in surface sum …

Sum frequency generation (SFG) vibrational spectroscopy is a unique surface/interface-
sensitive method, enabling the identification of chemical species and molecular structures …

We report the observation of infrared free induction decay (IR-FID) signal of the
antisymmetric modes around 2350 cm–1 of the gaseous CO2 molecules in air in the sum …

While in principle the frequency-domain and time-domain spectroscopic measurements
should generate identical information for a given molecular system, the inhomogeneous …

Characterization of real-time and ultrafast motions of the complex molecules at surface and
interface is critical to understand how interfacial molecules function. It requires to develop …

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 …

The difficulty in achieving high spectral resolution and accurate line shape in sum-frequency
generation vibrational spectroscopy (SFG-VS) has restricted its use in applications requiring …

CO adsorption and dissociation on “perfect” and “defect-rich” Ir (111) surfaces were studied
by a combination of surface-analytical techniques, including polarization-dependent (PPP …
