Quantum Dynamics as an Approach to Study Atomic and Molecular Structures of Some of The di-Atomic Molecules

Abstract

The theoretical studies of molecular structure using the methods of quantum mechanics form a vast and very active research area. It would be very difficult to try to cover all recent advances in this area within a single work. Most of the developments in the associated quantum-mechanics methodology are aimed at providing more and more accurate calculation of the structure of molecules, and this because the difficulties that were found to give the exact solution for Schrödinger equation. All this theoretical investigation of the molecular structure has introduce Wide range of application to the branch of material science and chemists who interested in this field. ** In chapter one Literature Survey has been introduced to cover the molecular physics study from old to modern ideas , beginning with the first attempts to know the atomic and molecular structures of materials and the effort of all scientist that contribute to this subject. ** In chapter two all the theories that concerned with the work has been handled beginning with dividing the branch of physics that dealing with molecular structure into two sections: - Molecular mechanics which use the laws of classical physics.
