The technique of H(D) atom photofragment translation spectroscopy has been used to investigate the dissociation of jet-cooled HOD molecules following excitation to individual rovibrational levels of its ~ C(B1) Rydberg state near 124 nm. Spectra have been recorded for both the DþOH and HþOD dissociation channels. The branching ratios between OH/OD(X 2 , high v, low N), OH/OD(X 2 , low v, high N...

Inelastic effects in the Coulomb blockade and Kondo regimes of electron transport through molecular junctions are considered within a simple nonequilibrium equation-of-motion EOM approach. The scheme is self-consistent and can qualitatively reproduce the main experimental observations of vibrational features in the Coulomb blockade H.

Potential energy surfaces for the ground and excited electronic states responsible for the Hartley continuum of ozone are used to obtain quadratic, cubic, and quartic force constants. Vibrational dependence of rotational constants to sixth order is calculated by perturbation theory. The spectroscopic constants enable computation of rovibronic energy levels. Overlap of ground state and excited s...

Optical properties of symmetry-forbidden π-π transitions in benzene are calculated with the time-dependent density functional theory (TDDFT), using an adiabatic LDA functional. Quantities calculated are the envelopes of the Franck-Condon factors of the vibrationally promoted transitions and the associated oscillator strengths. The strengths, which span three orders of magnitude, are reproduced ...

We have performed microwave reflection experiments on a charge-phase qubit coupled to an LC oscillator. We find that the system behaves like an artificial molecule showing vibronic sideband transitions. The reflected signal is determined by a combination of the Franck-Condon principle and resolved-sideband cooling or heating of the oscillator.

A treatment of oneor two-photon fluorescence excitation spectra is described using the vibration-rotation coupling of zeroth order states in the excited electronic state and nonadiabatic coupling to the ground state. Using perturbation theory, experimental harmonic frequencies, an anharmonic force field, and various theoretical Coriolis coupling constants, a quasistationary molecular eigenstate...
