Review of quantum mechanics from a postulational viewpoint; variational and matrix methods; time independent and time-dependent perturbation theory; applications to molecular systems including potential energy surfaces and reaction pathways. Review fundamental concepts and laws of thermodynamics and kinetics. Learn and describe concepts of chemical potential, internal energy and chemical equilibrium of the system. Essence of kinetics to describe changes of chemical system with time, i.e., rates of chemical reactions, dealing with molecules in motion, collisions and diffusion of gases, and how to establish rate expression.
