The effect of the Coriolis interaction upon the sharing of energy between rotational and vibrational excitation
during an electronic transition is considered with particular emphasis on recoil-induced excitation during
photoionization. If there is a large change in equilibrium bond length upon ionization, then Coriolis coupling
leads to a significant transfer...
The photoelectron spectra of a series of ketone
compounds have been investigated in the gas phase. Core
ionization energies were measured to probe the effects of
molecular size and connectivity number on core ionization
It was found that core ionization energies roughly
decrease with increasing connectivity number as expected....
The carbon is photoelectron spectrum of CO₂ has been measured with very high photon energy resolution. The natural lifetime of the carbon is hole state has been determined from a series of spectra taken at photon energies of 308, 320, and 330 eV. The measured values of the lifetimes show...
A new x-ray source capable of operating at up to 80
watts has been designed and developed, and put to use with
the Oregon State University Cylindrical Electrostatic
Analyzer. The new source produces over four times the
photoelectron intensity of its predecessor, from gaseous
samples, and accommodates a wider selection...
The core-electron ionization potentials for mono- and
di(trifluoromethyl)benzene, for chlorofluoromethanes and for
chlorine have been measured in order to give information on
the electron distribution in these molecules and to investigate
differences between the inductive effect of fluorine
and that of CF3. For trifluoromethylbenzene the measured
ionization potentials in eV...
The satellite structure ("shake-up") present in the X-ray
photoelectron spectra of several planar molecules containing
double bonds has been investigated in the gas phase.
This set consists of three five-membered heterocyclic
molecules, ethylene and two of its fluorinated analogs, and
benzene with three of its fluorinated analogs. In addition,
The photoelectron spectra of a series of halogenated
molecules have been investigated in the gas phase. Both
core-ionization energies and Auger kinetic energies were
measured to probe the nature of the interaction that holds
a core electron to the molecule.
It was found that satellite structure (shake) could be
