Benzonitrile: Electron affinity, excited states, and anion solvation.
We report a negative-ion photoelectron imaging study of benzonitrile and several of its hydrated, oxygenated, and homo-molecularly solvated cluster anions. The photodetachment from the unsolvated benzonitrile anion to the X̃(1)A1 state of the neutral peaks at 58 ± 5 meV. This value is assigned as the vertical detachment energy (VDE) of the valence anion and the upper bound of adiabatic electron ...
متن کاملThe role of excited Rydberg States in electron transfer dissociation.
Ab initio electronic structure methods are used to estimate the cross sections for electron transfer from donor anions having electron binding energies ranging from 0.001 to 0.6 eV to each of three sites in a model disulfide-linked molecular cation. The three sites are (1) the S-S sigma(*) orbital to which electron attachment is rendered exothermic by Coulomb stabilization from the nearby posit...
متن کاملPhotodetachment microscopy to an excited spectral term and the electron affinity of phosphorus
A beam of P− ions produced by a cesium sputtering ion source was photodetached in the presence of an electric field, with a single-mode ring dye laser. Neutral P can be produced at one or the other of the fine-structure sub-levels of its 3s23p3 2Do excited term. This is the first atomic photodetachment microscopy experiment with excitation of the parent neutral atom out of the fundamental spect...
متن کاملExcited states of 19Mg
We have calculated energies of the first two excited states of 19Mg by using a model that was previously successful for the ground state. Computed excitation energies are 1.12 and 1.54 MeV for (3/2−) and (5/2−), respectively—somewhat in disagreement with values of 1.38 and 2.14 MeV from a recent experiment.

متن کاملPhotoelectron spectroscopy of FeO and FeO2 : Observation of low-spin excited states of FeO and determination of the electron affinity of FeO2
The photoelectron spectra of FeO and FeO2 2 are obtained at 3.49 eV photon energy. Transitions to the ground state ~D! and three low-lying excited states ~S, S, and D! of FeO are observed. The two low-spin excited states found at 6770 and 8310 cm above the ground state, respectively, have not been observed before. The two S states, characteristic of detachment of a nonbonding electron from the ...
