Forty-five years of chemical discovery including a golden quarter-century.
TL;DR: In the 1970s, probably as a direct result of the world abandoning the gold standard, the chemistry of gold was awakened after a long sleep as discussed by the authors, and gold binding to organic π acids have intrigued my group and other gold chemists during this period.

Excited states of polar negative ions
TL;DR: In this article, the spectra of electronically excited states of strongly polar negative ions are discussed in terms of general features that may be predicted for such systems, and the general properties are then studied through a systematic treatment of lithium halide and lithium hydride anions.

Electron Attachment Processes
L.G. Christophorou,D.L. McCorkle,A. A. Christodoulides +2 more
- 01 Jan 1984
TL;DR: In this article, the authors discuss the effects of temperature on dissociative electron attachment processes and negative ions formed by ion-pair processes and by collisions of molecules with ground state and Rydberg atoms.

Determination of electron binding energies of ground-state dipole-bound molecular anions.
TL;DR: Two simple models for the determination of electron binding energies of several dipole-bound negative ions from field-detachment experiments and charge-transfer formation-rate-constant measurements in collisions between cold neutral molecules and Rydberg atoms are described.

Dipole binding: An experimental test for small cluster structure calculations
Charles Desfrançois,H. Abdoul-Carime,N. Khelifa,Jean-Pierre Schermann,Valérie Brenner,Philippe Millié +5 more
TL;DR: In this paper, an experimental method for the discrimination between nearly degenerate isomers of size selected clusters of closed-shell polar molecules is presented based upon electron attachment properties of dipole fields since a minimum value (≊2.5 D) of molecular dipoles is required for electron binding.

The Theory of Scattering by a Rigid Rotator
A. M. Arthurs,Alexander Dalgarno +1 more
TL;DR: A theory of scattering by a rigid rotator in which the coupling between the different energy levels of the rotator is taken into account is formulated and explicit expressions, which do not depend upon the magnetic quantum numbers, are obtained for various elastic and inelastic cross-sections as discussed by the authors.

Bound states of a charged particle in a dipole field
O H Crawford
- 01 Jun 1967
TL;DR: In this article, it was shown that each symmetry class of states has its own threshold value of K such that states of that symmetry exist if, and only if, K exceeds the critical minimum.

Critical binding of an electron to a non-stationary electric dipole
TL;DR: In this paper, the critical dipole moment for electron binding to a finite no 1-stationary electric dipole was determined, and the critical moment was found to depend on the masses and separation of the dipole charges.

On the existence of negative ions of nonionic polar molecules: Studies of HF−, H2O−, HCN−, (HF)−2, H3NO− and CH3CN−*
TL;DR: In this paper, it was shown that nonionic polar molecules with sufficiently large dipole moments can form stable anions by the attachment of electrons in their dipole fields, and the resulting electron affinities are found to be considerably smaller than for ionic molecules with comparable dipole moment.

Minimum dipole moment required to bind an electron to a finite dipole
J.E. Turner,K. Fox +1 more
TL;DR: The minimum dipole moment required for electronic binding to a dipole has been found in this paper, with weaker dipoles having no negative energy states, and the minimum Dmin = 0.6393 eao = 1.625 × 10−18 esu-cm.
