Single 4,7,12,15-tetrakis[2.2]paracyclophane were deposited on NiAl(110) surface at 11 K. Two adsorbed species with large and small conductivities were detected by the scanning tunneling microscope (STM). Their vibrational properties were investigated by inelastic electron tunneling spectroscopy (IETS) with the STM. Five vibrational modes were observed for the species with the larger conductivi...

Electron transport in single-walled carbon nanotubes (SWCNTs) is extremely sensitive to environmental effects. SWCNTs experiencing an inhomogeneous environment are effectively subjected to a disorder potential, which can lead to localized electronic states. An important element of the physical picture of such states localized on the nanometer-scale is the existence of a local vibronic mainfold ...

For the lithium dimer we calculate cross sections for absorption of radiation from the vibrational-rotational levels of the ground X 1Σ+g electronic state to the vibrational levels and continua of the excited A 1Σ+u and B Πu electronic states. Theoretical and experimental data are used to characterize the molecular properties taking advantage of knowledge recently obtained from photoassociation...

We present applications of extreme ultraviolet (XUV) single-order laser harmonics to gas-phase ultrafast photoelectron spectroscopy. Ultrashort XUV pulses at 80 nm are obtained as the 5th order harmonics of the fundamental laser at 400 nm by using Xe or Kr as the nonlinear medium and separated from other harmonic orders by using an indium foil. The single-order laser harmonics is applied for re...

For the lithium dimer we calculate cross sections for absorption of radiation from the vibrational-rotational levels of the ground X Σg electronic state to the vibrational levels and continua of the excited A Σu and B Πu electronic states. Theoretical and experimental data are used to characterize the molecular properties taking advantage of knowledge recently obtained from photoassociation spe...

Multidimensional optical techniques, the focus of this special issue, are analogues of their NMR counterparts; that is, rather than using spin transitions as little spies within a molecule, we use vibrational or optical transitions. Similar to NMR, the spectroscopic states often respond in a very sensitive way to their chemical environment. By modeling the coupling of one of these states to eit...
