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

Concept of polarity of free radicals in reactions of addition to olefins
TL;DR: The concept of polarity (nucleo and electrophilicity) of free radicals in processes of addition to unsaturated substrates was developed within the framework of the method of qualitative potential energy surfaces on the basis of an analysis of the interaction of diabatic surfaces for reactions of free-radical addition to olefins as mentioned in this paper.

Laser Photodissociation Techniques for Studying Ion Spectroscopy and Structure
TL;DR: In this article, the photodissociation spectra of gas-phase ions as a function of wavelength were used to provide experimental access to questions of ion structure, rearrangements, electronic and vibrational properties, and thermochemistry, and a link between mass spectrometry and optical spectroscopy.

The band 12 issue of norbornane: a study of higher shake-up states.
TL;DR: A tentative description in terms of ultrafast nuclear dynamical effects and autoionization processes has become more plausible and the band-12 issue of norbornane is still open for further discussion.

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.
