Generalized Heitler-London theory with exchange energy by the surface integral method: an application to the alkali metal dimer cations
TL;DR: In this article, the generalized Heitler-London theory is used to calculate the lowest gerade and ungerade potential energy curves of the alkali metal dimer cations Li 2 +, Na 2 +, K 2+, Rb 2 + and Cs 2 +.
Journal ArticleDOI
Corresponding states principle and van der Waals potentials of Zn2, Cd2, and Hg2.
TL;DR: There are indications that the ground state Hg2 potential predicted by the present study is possibly the most accurate to date and both Zn2 and Cd2 bond lengths predicted are in good agreement with the quantum Monte Carlo results.
Journal ArticleDOI
Boundary condition determined wave functions for the ground states of one-and two-electron homonuclear molecules
TL;DR: In this paper, simple analytical wave functions satisfying appropriate boundary conditions are constructed for the ground states of one-and two-electron homonuclear molecules, and the resulting wave function is almost identical to the Guillemin-Zener wave function which is known to give very good energies.
Journal ArticleDOI
Communication: A simple full range analytical potential for H2b3∑u+, H–He 2∑+, and He21∑g+
TL;DR: The Tang-Toennies potential for the weakly interacting systems H2b(3)Σu (+), H-He (2) Σ(+), and He2 (1)(+) is extended down to the united atom limit of vanishing internuclear distance, compared with the most recent ab initio calculations.
Journal ArticleDOI
Asymptotic theory for the 2∑u Van der Waals potentials of alkali dimer cations
TL;DR: The 2 ∑ u state Van der Waals potentials of alkali dimer cations were calculated from the asymptotic exchange and polarization energies as discussed by the authors, and the results agree with accurate CI calculations.
