Accurate studies on the full vibrational energy spectra and molecular dissociation energies for some electronic states of halogen molecule

doi:10.1088/1674-1056/20/2/023102

Abstract This paper obtains accurate vibrational spectroscopic constants and full vibrational energy spectrum by the algebraic method (AM) for some electronic states of halogen diatomic molecules. Motivated by the recent success of obtaining the dissociation energies of Li₂ molecule by using a new analytical formula, it further extends the formula to study the dissociation energies of halogen diatomic molecules. The results show that the AM spectrum and the theoretical dissociation energies agree well with RKR data and experimental data respectively.

Keywords: vibrational energy dissociation energy halogen molecule algebraic method
