Direct potential fit analysis of the X 1Σ+ ground state of CO
A collection of 21,559 highly precise spectroscopic line positions from pure rotational and vibration-rotational spectra for seven isotopomers of carbon monoxide in the X1sigma+ ground electronicExpand
On the direct determination of analytical diatomic potential energy functions from spectroscopic data: the X 1∑+ electronic states of NaF, LiI, CS, and SiS
Abstract Line positions available in the literature for vibrational-rotational and pure rotational transitions have been employed to determine accurate effective potential energy curves for theExpand
Improved potential energy curves and dissociation energies for HF, DF and TF
Abstract We have constructed new hybrid potential energy curves for the ground states of HF, DF and TF based primarily on the experimentally based potentials of Coxon and Hajigeorgiou which includeExpand
The Radial Hamiltonians for the X1Σ+ and B1Σ+ States of HCl
Abstract All literature vibration–rotational and pure rotational transition energies for the ground X1Σ+ electronic state of H35Cl, H37Cl, D35Cl, and D37Cl, along with the entire collection ofExpand
Isotopic dependence of Born-Oppenheimer breakdown effects in diatomic hydrides: The B1Σ+ and X1Σ+ states of HCl and DCl
Abstract A numerical procedure for reducing spectroscopic line positions to isotopically self-consistent radial Hamiltonian operators is applied to the X 1 Σ + and B 1 Σ + electronic states of theExpand
Improved direct potential fit analyses for the ground electronic states of the hydrogen halides: HF/DF/TF, HCl/DCl/TCl, HBr/DBr/TBr and HI/DI/TI
Abstract The potential energy and Born–Oppenheimer breakdown functions for the X1Σ+ ground electronic states of the hydrogen halides HF, HCl, HBr, and HI are reported in full analytic form. AllExpand
Accurate internuclear potential energy functions for the ground electronic states of NeH+ and ArH+

The number of bound vibrational levels in a diatomic molecule
Abstract A simple semiempirical expression has been developed for estimating the effective non-integer vibrational index at dissociation, υD, in diatomic systems. The expression is given by, υ D =Expand
The vibrational index at dissociation: An extended treatment
Abstract The simple empirical expression recently proposed Hajigeorgiou (2013) [1] for estimating the effective non-integer vibrational index at dissociation in a diatomic molecule, has been revisedExpand
