The photon-driven substrate-mediated dissociation of N2O on thin MgO films grown on an Ag(100) crystal has been investigated with postirradiation thermal desorption spectroscopy (TDS). After excitation with 248 nm photons, we observe the simultaneous

The optical properties of single-wall carbon nanotube sheets in the far-infrared have been investigated with THz time-domain spectroscopy. Over a wide frequency range from 1 THz to 40 THz, the complex dielectric function of the nanotube sample has be

Time-resolved THz spectroscopy is employed to investigate the ultrafast electron dynamics in gaseous Ar, SF 6 , and an Ar–SF 6 mixture following ionization by an intense femtosecond laser pulse. The THz response of the free electrons can be describ

The wetting layer of DO on Ru(000 1) has been reanalyzed with ab initio molecular dynamics and full-potential calculation. The work function change induced by DO overlayers clearly favors the picture of molecular wetting rather than partial dissociat

Absorption of femtosecond near-infrared laser pulses in the surface near region of Ru(001) covered with atomic hydrogen induces recombinative desorption of its molecular species. The ultrafast time scale of this surface reaction as evidenced by two-p

In light of the controversial discussion of the interfacial structure of water on metal surfaces, adsorption of D 2 O on Ru(0 0 1) is investigated using sum-frequency generation vibrational spectroscopy. In contrast to a recent theoretical study clai

Using femtosecond time-resolved two-photon photoelectron spectroscopy we have studied the dynamics of photoexcited electrons injected from a Cu(1 1 1) substrate into the conduction band of ultrathin ice layers. Ultrafast localization of the injected

Anion femtosecond photoelectron spectroscopy (FPES) has been used to monitor intramolecular electronic relaxation dynamics following the excitation of the C 2Πg←X 2Πu 000 electronic transition in C6−. The time-dependent photoelectron spectra pr

Femtosecond stimulated emission pumping in conjunction with femtosecond photoelectron spectroscopy is used to monitor dynamics within I2−(CO2)4 following coherent vibrational excitation of the I2− chromophore. Femtosecond pump and dump pulses cre

The dynamics of the cluster precursors to charge-transfer-to-solvent (CTTS) states have been studied in clusters of iodide with xenon, water, D 2 O, ammonia and methanol using femtosecond photoelectron spectroscopy. The dynamics of these states diffe
