Calculation of New Five Parameters Potential and Dissociation Energy for (X1Σ+- A1Π) Band System of Diatomic Molecule

Abstract

" The present work concerns by study of potential curve and dissociation energy for Diatomic moleculeSiO which is founded in supernova ejecta type II. Dissociation energy had been calculated theoretically for ground state X1Σ+ and excited state A1Π of SiO molecule by Gaydenrelation and by depending on spectroscopic constants for this molecule. Our results are compared with experimental results and appear good convergence, also showed an important effect for bond length (r) for occur the dissociation. The potential of this molecule is studied in this work by using new five parameters potential function, the results appear that potential curve of SiO molecule for ground state X1Σ+ and excited state A1Πconverge with experimental result"
