Resonant photoelectron spectroscopy of Au2(-) via a Feshbach state using high-resolution photoelectron imaging.

Photodetachment cross sections are measured across the detachment threshold of Au2(-) between 1.90 and 2.02 eV using a tunable laser. In addition to obtaining a more accurate electron affinity for Au2 (1.9393 ± 0.0003 eV), we observe eight resonances above the detachment threshold, corresponding to excitations from the vibrational levels of the Au2(-) ground state (X(2)Σu(+)) to those of a meta...

Vibronic effects in the photon energy-dependent photoelectron spectra of the CH3CN 2 dipole-bound anion

Photoelectron spectra are reported for the ‘‘dipole-bound’’ CH3CN 2 negative ion at three photodetachment energies ~1.165, 2.331, and 3.496 eV!, where the anion is prepared by photodissociation of the I•CH3CN ion–molecule complex. While all three spectra are dominated by a single feature centered near zero electron binding energy, as expected for a dipole-bound anion, vibrational structure is a...

Real-time observation of intramolecular proton transfer in the electronic ground state of chloromalonaldehyde: an ab initio study of time-resolved photoelectron spectra.

The authors report on studies of time-resolved photoelectron spectra of intramolecular proton transfer in the ground state of chloromalonaldehyde, employing ab initio photoionization matrix elements and effective potential surfaces of reduced dimensionality, wherein the couplings of proton motion to the other molecular vibrational modes are embedded by averaging over classical trajectories. In ...

Vibrational branching ratios and shape resonant photoionization dynamics

Vibrational branching ratios and photoelectron asymmetry parameters for alternative vibrational modes in the photoionization of N 20 ( 7 u1 ) have been studied using accurate photoelectron continuum orbitals. Earlier dispersed ionic fluorescence measurements [E. D. Poliakoff, M. H. Ho, M.G. White, and G. E. Leroi, Chern. Phys. Lett. 130, 91 ( 1986)] revealed strong non-Franck-Condon vibrational...

Vibrational state-selective autodetachment photoelectron spectroscopy from dipole-bound states of cold 2-hydroxyphenoxide: o-HO(C6H4)O(-).

We report a photodetachment and high-resolution photoelectron imaging study of cold 2-hydroxyphenoxide anion, o - HO(C6H4)O(-), cooled in a cryogenic ion trap. Photodetachment spectroscopy revealed a dipole-bound state (DBS) of the anion, 25 ± 5 cm(-1), below the detachment threshold of 18 784 ± 5 cm−1 (2.3289 ± 0.0006 eV), i.e., the electron affinity of the 2-hydroxyphenoxy radical o - HO(C6H4...
