Abstract

Low-energy photoelectron imaging spectra of HCS{sub 2}{sup −} are reported for the first time. Vibrationally resolved photodetachment transitions from the ground state of HCS{sub 2}{sup −} to the ground state and low-lying excited states of HCS{sub 2} are observed. Combined with the ab intio calculations and Franck-Condon simulations, well-resolved vibrational spectra demonstrate definitive evidence for the resolution of the ground-state and excited states of HCS{sub 2} radical in the gaseous phase. The ground state and two low-lying excited states of HCS{sub 2} radical are assigned as {sup 2}B{sub 2}, {sup 2}A{sub 2}, and {sup 2}A{sub 1} states, respectively. The adiabatic electron affinity is determined to be 2.910 ± 0.007 eV. And the term energies of the excited states, T{sub 0} = 0.451 ± 0.009 eV and 0.553 ± 0.009 eV, are directly measured from the experimental data, respectively. Angular filtering photoelectron spectra are carried out to assist in the spectral band assignment.

Anion photoelectron spectroscopy of B{sub 2}N{sup {minus}}

Journal Article Asmis, K; Taylor, T; Neumark, D - Journal of Chemical Physics

Vibrationally resolved 355 and 266 nm anion photoelectron spectra of B{sub 2}N are presented. Photodetachment to two electronic states of linear B{endash}N{endash}B is observed and, aided by electronic structure calculations, assigned to the {tilde X}&hthinsp;{sup 1}{Sigma}{sub g}{sup +}{r_arrow}{tilde X}&hthinsp;{sup 2}{Sigma}{sub u}{sup +}+e{sup {minus}} and {tilde X}&hthinsp;{sup 1}{Sigma}{sub g}{sup +}{r_arrow}{tilde A}&hthinsp;{sup 2}{Sigma}{sub g}{sup +}+e{sup {minus}} transitions. The electron affinity of B{sub 2}N is 3.098{plus_minus}0.005&hthinsp;eV and the {tilde A}&hthinsp;{sup 2}{Sigma}{sub g}{sup +} term energy T{sub 0} is 0.785{plus_minus}0.005&hthinsp;eV. Observation of excitations involving uneven quanta of the antisymmetric stretching mode (v{sub 3}) indicates a breakdown of the Franck{endash}Condon (FC) approximation and results frommore »« less

Slow photoelectron velocity-map imaging spectroscopy of the Fe{sub 3}O{sup –} and Co{sub 3}O{sup –} anions

Journal Article Kim, Jongjin; Weichman, Marissa - Journal of Chemical Physics

We report high-resolution photoelectron spectra of the transition metal suboxide clusters Fe{sub 3}O{sup −} and Co{sub 3}O{sup −}{sub .} The combination of slow electron velocity-map imaging and cryogenic cooling yields vibrationally well-resolved spectra, from which we obtain precise values of 1.4408(3) and 1.3951(4) eV for the electron affinities of Fe{sub 3}O and Co{sub 3}O. Several vibrational frequencies of the neutral ground state Fe{sub 3}O and Co{sub 3}O clusters are assigned for the first time, and a low-lying excited state of Fe{sub 3}O is observed. The experimental results are compared with density functional electronic structure calculations and Franck-Condon spectral simulations, enablingmore »« less

High-resolution photoelectron imaging spectroscopy of cryogenically cooled Fe{sub 4}O{sup −} and Fe{sub 5}O{sup −}

Journal Article Weichman, Marissa; DeVine, Jessalyn - Journal of Chemical Physics

We report high-resolution photodetachment spectra of the cryogenically cooled iron monoxide clusters Fe{sub 4}O{sup −} and Fe{sub 5}O{sup −} obtained with slow photoelectron velocity-map imaging (cryo-SEVI). Well-resolved vibrational progressions are observed in both sets of spectra, and transitions to low-lying excited states of both species are seen. In order to identify the structural isomers, electronic states, and vibrational modes that contribute to the cryo-SEVI spectra of these clusters, experimental results are compared with density functional theory calculations and Franck-Condon simulations. The main bands observed in the SEVI spectra are assigned to the {sup 15}A{sub 2}←{sup 16}B{sub 2} photodetachment transition ofmore »« less

Anion Photoelectron Spectroscopy of Semiconductor Clusters

Thesis/Dissertation Xu, Cangshan

Semiconductor and related clusters are studied by anion photoelectron spectroscopy. Vibrationally-resolved photoelectron spectra of carbon (C₄^-, C₆^-, and C₈^-) and silicon (Si₃^- - Si₇^-) clusters were measured at various photodetachment wavelengths. Electron affinities, term energies, and vibrational frequencies for the ground and excited electronic states of the neutral clusters have been obtained. The assignments of excited electronic states were aided by ab initio calculations, as well as measurements of photoelectron angular distributions. Besides clusters of pure elements, mixed group III-V clusters are also investigated. Small indium phosphide clusters having 2-8 atoms are studied using anion photoelectron spectroscopy of In_xP_y^- (x,y=1-4).more »« less
Dipole-bound excited states and resonant photoelectron imaging of phenoxide and thiophenoxide anions

Journal Article Zhu, Guo-Zhu; Qian, Chen-Hui; Wang, Lai-Sheng - Journal of Chemical Physics

We report photodetachment and resonant photoelectron-imaging studies of cryogenically cooled phenoxide (C₆H₅O^–) and thiophenoxide (C₆H₅S^–) anions. In a previous study, a dipole-bound excited state was observed for C₆H₅O^– at 97 cm^–1 below the detachment threshold. Eight resonant photoelectron spectra were obtained via excitations to eight vibrational levels of the dipole-bound state (DBS) followed by autodetachment. In this paper, we present a complete photodetachment spectrum of C₆H₅O^– covering a spectral range 2600 cm^–1 above the detachment threshold and revealing nine additional vibrational resonances of the DBS. We also report the first observation of a dipole-bound excited state for C₆H₅S^–, 39 cm^–1more »« less
