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

Collisional activation by fourier-transform mass spectrometry
David H. Russell,D.L. Bricker +1 more
TL;DR: In this article, the charge transfer reactions between translationally excited polyatomic ions and the neutral target gas used for collisional activation/collision-induced dissociation are described, and an additional area where Fourier transform mass spectrometry can be used to probe the fundamentals of ion/neutral interactions, viz., target gas excitation which competes with collision induced dissociation.

Vacuum ultraviolet photoionization mass spectrometric study of cyclohexene.
TL;DR: The present research provides a clear picture of the photoionization and dissociation processes of cyclohexene in the 8- to 15.5-eV photon energy region.

The use of 2s-derived molecular orbitals in identifying surface hydrocarbons using photoelectron spectroscopy
TL;DR: In this paper, it is shown from the photoelectron spectra of a range of hydrocarbons adsorbed on a Mo (100) surface obtained using synchrotron radiation that this differential shift is usually less than ≈ 0.5 eV.

Doubly protonated benzene in the gas phase.
TL;DR: Structural aspects and the unimolecular fragmentations of doubly protonated benzene are studied by means of tandem-mass spectrometry and it is suggested that EI of 1,3-cyclohexadiene leads to the singlet state of doubfully protonate benzene, whereas EIof 1,4-cyclosine yields a mixture of singlet and triplet states.

The electronic states of but-2-yne studied by VUV absorption, near-threshold electron energy-loss spectroscopy and ab initio configuration interaction methods
Michael H. Palmer,I. C. Walker +1 more
TL;DR: In this paper, the authors used a triple zeta+polarisation basis set, augmented by diffuse (Rydberg) orbitals, to generate the theoretical singlet and triplet energy manifolds.

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.
