Journal ArticleDOI
The alkaline earth dimer cations (Be2 +, Mg2 +, Ca2 +, Sr2 +, and Ba2 +). Coupled cluster and full configuration interaction studies†
Huidong Li,Hao Feng,Weiguo Sun,Yi Zhang,Qunchao Fan,Kirk A. Peterson,Yaoming Xie,Henry F. Schaefer +7 more
TL;DR: In this article, both coupled cluster and full configuration interaction methods were used to describe the M2+ systems and the results for the unknown dissociation energies were obtained for the neutral alkaline earth dimers.
Journal ArticleDOI
Studies on the vibrational and rovibrational energies and vibrational force constants of diatomic molecular states using algebraic and variational methods
TL;DR: In this paper, an algebraic method was proposed to generate a converged full vibrational spectrum from limited energy data, and a potential variational method was suggested to produce the vibrational force constants f n and rotational spectrum constants using the perturbation formulae and the AM vibrational constants.
Journal ArticleDOI
Studies on full vibrational spectra and dissociation energies of some diatomic molecular electronic states using algebraic approaches
TL;DR: In this article, an algebraic energy method (AEM) is suggested as an alternative theoretical approach to generate molecular dissociation energy D e, which is used to evaluate accurate full vibrational energy spectra {E υ} and D e in this study for 14 diatomic electronic states of Li2, Na2, Rb2, K2 and Sr2 molecules.
Journal ArticleDOI
Accurate studies on dissociation energies of diatomic molecules
Weiguo Sun,QunChao Fan,Weiyi Ren +2 more
TL;DR: In this paper, the molecular dissociation energies of some electronic states of hydride and N2 molecules were studied using a parameter-free analytical formula suggested in this study and the algebraic method (AM) proposed recently.
Journal ArticleDOI
Accurate studies on the full vibrational energy spectra and molecular dissociation energies for some electronic states of N 2 molecule
TL;DR: In this article, a new analytical formula for obtaining accurate molecular dissociation energy based on the LeRoy and Bernstein's energy expression in dissociation limit was proposed, and a set of full vibrational energy spectra for some electronic states of N 2 molecule were studied using the algebraic method.
