TLDR
In this article, the π-ionization potentials of unsubstituted acetylenes can be parametrized in terms of a LCBO-model using the PE-spectra of triacetylene, methyldiacetylene and dimethylacetylene.Abstract:
The PE.-spectra of triacetylene 1 (3), methyldiacetylene 2 (2), dimethylacetylene 3 (1) and dimethyldiacetylene 3 (2) have been recorded. The π-ionization potentials of the unsubstituted acetylenes can be parametrized in terms of a LCBO-model.read more

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.
