A number of reasons for the appearance of anomalous intensities in zero-kinetic-energy (ZEKE) spectroscopy are briefly reviewed and extended. Particular attention is paid to a recent paper of Matsui, Behm, and Grant in which the authors detect, in th

NH 4 and ND 4 have been the subject of many studies, experimental and theoretical. Fuke et al. have recently recorded the photoionization cross-section at threshold for ND 4 revealing unusual behavior. Based on this observation, theoretical calculati

A model is developed to determine the rate of electron transfer between high n molecular Rydberg states and ions of the same species under zero kinetic energy pulsed field ionization (ZEKE‐PFI) experimental conditions. A simple hydrogenic model is

The Rydberg state reaction H*2+H2→H+3+H+e− was studied by exciting the (X 2∑+g)np,v=0,J Rydberg states with n=30–70 by double resonance excitation via the E,F 1∑+g,v=0,J=1 level and by detecting the product ions or electrons. The results ar

Recent experimental results reporting lifetimes of very high Rydberg states of phenanthrene and deuterated phenanthrene together with a theoretical analysis are examined critically. Weaknesses in the theoretical model are pointed out, in particular t

It is shown that under the usual conditions of zero‐electron‐kinetic‐energy, pulsed field ionization (ZEKE–PFI) spectroscopy the lifetimes of very high‐lying Rydberg states are increased by at least approximately the factor n (in addition t

The transition energies for ethylene have been calculated via configuration interaction including all singly excited configurations (CIS) using a variety of basos sets. The minimum requirement for a satisfactory basis set is 6-311 (2+)G * having two
