Studies on the full vibrational energy spectra and molecular dissociation energies for some electronic states of Na2 molecule
Na2分子部分电子态的完全振动能谱和离解能的精确研究

Modern experimental methods or accurate quantum theory methods usually may obtai n a vibrational energy subset E v] containing m energies, but it may be very difficult to have all the excited high-lying vibrational energies for t he electronic states of most diatomic molecules. Since the full vibrational spec trum and the molecular dissociation energies of the electronic states of Na 2 molecu le ar e very important in many studies and applications, the vibrational spectroscopic constants and the full vibrational spectra of some electronic states of Na 2 m olecules are acqnired using the algebraic method (AM), and the dissociation ener gy (D E) of these states are obtained using the algebraic energy method (AEM). The res ults show that AM can give accurate vibrational spectroscopic constants and co rre ct full vibrational energy spectrum {E v} from experimental vibrational ene rgy subs et E v], and the molecular dissociation energies obtained using the AEM have much better accuracy than those generated using the vibrational constants given in the literature . The AEM can give reliable values of the dissociation energies for some excited electronic states whose DE may not be available in the literture.
