A recent investigation of nitrogen $1s$ ionization in ${\mathrm{N}}_{2}$ by 40-keV photons has shown that only 70% of the recoil-induced internal energy appears as kinetic energy of the two nitrogen ions that are produced following the Auger decay of

“Substituent effects” is an important and useful concept in organic chemistry. Although there are many approaches to parametrizing the electronic and steric effects of substituents, the physical basis for the parameters is often unclear. The purp

The interplay between Franck–Condon and recoil-induced vibrational excitation in core-electron photoionization has been investigated using generalized Franck–Condon factors. Three models for the vibrational wave functions have been considered: th

Three features of small-molecule photoelectron spectroscopy are considered (1) the atom from which a photoelectron is emitted must have a recoil momentum equal to that of the emitted electron. This is shared among the various modes of motion of the i

The carbon 1s photoelectron spectra of a series of aliphatic alkynes and alkenes that have the possibility of possessing two or more conformers have been recorded with high resolution. The two conformers of 2-hexyne and 4-methyl-1-pentyne, anti and g

Electrophilic addition to multiple carbon-carbon bonds has been investigated for a series of twelve aliphatic and aromatic alkenes and the corresponding alkynes. For all molecules, enthalpies of protonation and activation energies for HCl addition ac

A database of 77 adiabatic carbon 1s ionization energies has been prepared, covering linear and cyclic alkanes and alkenes, linear alkynes, and methyl- or fluoro-substituted benzenes. Individual entries are believed to carry uncertainties of less tha
