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

TL;DR: A direct method is presented which, independent of theory, experimentally probes the participation of multiple electronic continua in the SFI dynamics of polyatomic molecules, using saturated and unsaturated linear hydrocarbons to show how subcycle SFI of polyatomics can be directly resolved into its distinct electronic-continuum channels by above-threshold ionization photoelectron spectroscopy.

TL;DR: In this paper, the structure and reactions of radical cations of prototype alkanes such as ethane, propane, isobutane, neopentane, etc. were characterized based on simple symmetry considerations as well as the INDO MO calculations.

TL;DR: This work investigates the catalytic pyrolysis of guaiacol, a lignin model compound, using photoelectron photoion coincidence spectroscopy with synchrotron radiation, which allows for isomer-selective detection of reactive intermediates, and identifies fulvenone as the central reactive intermediate.

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.
