To study HX-negative molecule system in photo-detachment process, we have to determineitswave functionsby Linear Combination of Atomic Orbitals (LCAO)of H- and X-[3].
The ab initio method involves a more fundamental approach to solving the Schrodinger equation than does the semiempirical method, although there are some assumptions implicit in such calculations (16), The basic approximation of ab initio calculation is that the total wave function is a single Slater determinant and the resultant expression of the molecular orbitals is a linear combination of atomic orbital basis functions (LCAO): in other word, ab initio calculation can be initiated once a basis for the LCAO is chosen.
