The techniques of Fourier transform spectroscopy and high pressure mass spectrometry have been used to investigate the ionization energy (IP) of SF5via electron exchange reactions. An IP of 9.60±0.05 eV has been derived from this data, which is in disagreement with estimates from flowing afterglow...

Rotational-resolved pulsed field ionization-photoelectron study of NO+(A′1Σ,v+=0–17) in the energy range of 17.70–20.10 eV We have obtained partially rotationally resolved pulsed field ionization-photoelectron (PFI-PE) spectra of NO in the energy range of 17.70–20.10 eV, cover... Y Son...
Photoelectron spectra of benzo[a]pyrene and benzo[e]pyrene have been assigned on the basis ofab initioelectron propagator theory. Electron correlation effects are included in the partial third order approximation and agreement with experimental peaks is very close. To each ionization energy, there cor...
A value of 10.90{sub 9}{+-}0.01{sub 6} eV wasobtained for the adiabatic ionization energy (IE) of Cl{sub 2}O fromanalysis of the photoionization thresholds. The ClO radical was producedvia the reaction F + Cl{sub 2}O {yields} FCl + ClO and the PIE spectrum of ClO was measured ...

Some notable discrepancies with literature values are highlighted. The ground state of CP + is confirmed to be the X 3Π state arising from a ⋯π 3σ 1 configuration, with the ⋯ π 4 σ 0( 1Σ +) state lying 0.75 eV higher in energy. 展开 关键词:...
Ionization potentials (IPs) of biomolecular systems typically lie in the 8–10 eV (800–1,000 kJ/mole) energy range corresponding to the Vacuum Ultraviolet VUV spectral range. Two-photon (R2PI) ionization can be used for the determination of IPs in the case of molecular systems possessing chr...
Both tungsten and gallium are important materials for fusion energy research. In this work, a semi-empirical method is used to determine ionization energies (IE) of multiply charged W ions [A.E. Kramida, J. Reader, Ionization Energies of Tungsten Ions: W^2+ through W^71+, At. Data Nucl...
