Observation of vibrational excitation in photoelectron spectroscopy of HI + 211
نویسنده
چکیده
Using photoelectron spectroscopy in combination with synchrotron radiation, we have observed previously inaccessible vibrational excitation of HI+ X 2113,z, X 2111,2 final ionic states. The vibrational enhancement is shown to be caused by strongly predissociating autoionization resonances converging to HI+ A ?Z+. Molecular vibrational constants are extracted from the photoelectron spectra obtained at different excitation energies.

Autoionization and neutral dissociation of superexcited HI studied by two-dimensional photoelectron spectroscopy.
Two-dimensional photoelectron spectroscopy of hydrogen iodide (HI) has been performed in the photon energy region of 11.10-14.85 eV, in order to investigate dynamical properties on autoionization and neutral dissociation of Rydberg states HI*(RA) converging to HI+(A 2Sigma1/2(+)). A two-dimensional photoelectron spectrum exhibits strong vibrational excitation of HI+(X 2Pi) over a photon energy ...
متن کاملTime-resolved photoelectron imaging of iodide-nitromethane (I-·CH3NO2) photodissociation dynamics.
Femtosecond time-resolved photoelectron spectroscopy is used to probe the decay channels of iodide-nitromethane (I-·CH3NO2) binary clusters photoexcited at 3.56 eV, near the vertical detachment energy (VDE) of the cluster. The production of I- is observed, and its photoelectron signal exhibits a mono-exponential rise time of 21 ± 1 ps. Previous work has shown that excitation near the VDE of the...
متن کاملSpectroscopic investigation of Al2N and its anion via negative ion photoelectron spectroscopy.
Negative ion photoelectron spectroscopy was used to elucidate the electronic and geometric structure of the gaseous Al2N/Al2N- molecules, using photodetachment wavelengths of 416 nm (2.977 eV), 355 nm (3.493 eV), and 266 nm (4.661 eV). Three electronic bands are observed and assigned to the X2Sigma(u)+ <-- X1Sigma(g)+, A2Pi(u) <-- X1Sigma(g)+, and B2Sigma(g)+ <-- X1Sigma(g)+ electronic transiti...
متن کاملResonant 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...
متن کاملPhotodissociation of triplet and singlet states of the CCO radical
The triplet and singlet states of the ketenylidene ~CCO! radical are investigated using fast radical beam photofragment translational spectroscopy, in which CCO is generated by laser photodetachment of CCO and subsequently photodissociated, and anion photoelectron spectroscopy. In the photodissociation experiment, two bands in which the upper state of CCO predissociates are studied. Photodissoc...
