In this paper, the experimental valence ionisation energies of 143 hydrocarbons, CnHm, have been determined from their He (IIα) (40.80 eV) and He (Iα)(21.22 eV)-excited photoelectron spectra.Abstract:
Experimental valence ionisation energies of 143 hydrocarbons, CnHm, have been determined from their He (IIα) (40.80 eV) and He (Iα) (21.22 eV) excited photoelectron spectra. Ionization energies, usually up to 26 eV are given in tabular form for 108 hydrocarbons with n≤6, together with their (tentative) assignment. The ionization energies up to approximately 25 eV, of 35 selected hydrocarbons with 7≤n≤10, are presented by means of their He (IIα) photoelectron spectra.read more

Inverted hyperconjugation in symmetrical 1,4-dihalocubanes
TL;DR: In this paper, the PE spectrum of cubane 1 is divided into two sets separated by a 3 eV gap extending from ∼ -10.5 eV to ∼ -13.5eV, and cubane substituents with np AO basis energies falling into this gap will hyperconjugate appreciably with both sets.

Electron Transfer Photochemistry of a Bridged Norcaradiene: A Mechanistic Probe for Radical Cation Nucleophilic Capture
TL;DR: In this paper, the radical cation of tricyclo[4.3.1.01,6]deca-2,4-diene (3) can be generated by electron transfer to 1,4dicyanobenzene (DCB) in acetonitrile/methanol; the species is captured by regiospecific nucleophilic attack of methanol in the 2-and 5-) position.

Removing electrons from more than one orbital: direct and indirect pathways to excited states of molecular cations
TL;DR: In this article, the authors measured both direct and indirect ionization to excited states of the molecular cations, and found that the energy gap between non-dissociative and dissociative states plays an important role in determining the amount of excited state ionization.

Ultra-violet photoelectron data on the complete valence shells of molecules recorded using filtered 30.4 nm radiation
TL;DR: In this paper, it was shown that in many molecules the summed binding energies of the molecular orbitals built from 2s atomic orbitals may be divided up into atomic contributions which agree in magnitude with those obtained for the same atoms in other molecules.

High Resolution Molecular Photoelectron Spectroscopy. I. Fine Structure in the Spectra of Hydrogen and Oxygen
TL;DR: In this paper, a photo-electron spectrometer is described which uses focusing deflexion in a radial electrostatic field for energy analysis, and an over-all limit of about 0.002 eV is deduced as the smallest attainable line width in ordinary circumstances.
