Valence Ionization Energies of Hydrocarbons
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

Ultrafast photochemistry of cyclopentadiene: Competing hydrogen migration and electrocyclic ring closure
TL;DR: In this article, it was shown that cyclopentadiene relaxes from the initial 1B 2 state, excited at 240nm, within 37fs to the dark 2A 1 state; a doubly exponential decay (71 and 333fs) leads from there to S 0.

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.
