Spectroscopic Constants and Molecular Properties of Diatomic Carbides

Journal of Molecular Spectroscopy, 2004
Abstract Spectroscopic constants and molecular properties of the diatomic carbides BeC, BC + , BC, NaC, and MgC in their ground states have been studied in detail using hybrid HF/DF B3LYP method. The effect of basis set on spectroscopic constants and molecular properties have been studied systematically with the improvement of the quality of the ...

Spectroscopic Parameter and Molecular Constant Investigations on Low-Lying States of BeF Radical [PDF]

open access: yesInternational Journal of Molecular Sciences, 2012
The potential energy curves (PECs) of X2Σ+, A2Πr and B2Σ+ states of BeF radical have been investigated using the complete active space self-consistent-field (CASSCF) method, followed by the highly accurate valence internally contracted multireference configuration interaction (MRCI) approach at the correlation-consistent basis sets, cc-pV5Z for Be and ...

Molecular screening and spectroscopic constants

International Journal of Quantum Chemistry, 2009
The use of a semi-empirically determined orbital exponent is investigated in a 4-electron energy calculation of LiH. The results are compared to those of a 2-electron calculation by the same semi-empirical method. Selected spectroscopic constants are also calculated from the energy dependence upon internuclear distance.

Theoretical Study of Spectroscopic Constants and Molecular Properties of Diatomic Anions Using B3LYP Method

Computational and Theoretical Chemistry, 2003
Abstract Structure, spectroscopic constants and molecular properties of selected diatomic anions in their ground states have been studied in detail using HF/DF B3LYP method. The consistency of the calculated values of spectroscopic constants and molecular properties has been tested using four basis sets with improved quality.

Interpolated values of spectroscopic constants of asymmetric alkali molecules and molecular ions

The Journal of Chemical Physics, 1975
With a very simple interpolation procedure, a number of fundamental spectroscopic constants (ground-state energies, equilibrium distances, force constants, and frequencies) for asymmetric alkali molecules and alkali molecular ions are estimated, starting from the corresponding values of the symmetric molecules and ions.
