TLDR
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

On the formation of cyclopentadiene in the C3H5˙ + C2H2 reaction.
TL;DR: The formation of cyclopentadiene as the sole product from the allyl + acetylene reaction offers a direct path to the formation ofcyclic hydrocarbons under combustion relevant conditions and may lead to theformation of the smallest polycyclic aromatic molecule, naphthalene.

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.
