A variational algebraic method used to study the full vibrational spectra and dissociation energies of some specific diatomic systems

Analytical potential energy function study for the 41∏ electronic state of Na85Rb molecule

“…Here is a simple characterization of variational algebraic energy consistent method (VAECM) which is improved by combining the Sun's energy consistent-method (ECM) [26] and variational algebraic method (VAM) [36].…”

“…In order to improve the reliability of the PECs especially for the long-range part correlating to the dissociation limit, the full vibrational energies { } u E , for which high-lying data are lacking experimentally for many cases of diatomic molecules, are essential parameters. Here, we are using the variational algebra method (VAM) [36] to determine the full vibration energies { } u E VAM and dissociation energy D .…”

“…e VAM To offset the probable error hidden in experimental data, a tiny quantity dE is an essential part of data analysis and is added to each vibrational energy. This can be expressed in matrix form [36] ( )…”
