# Chapter 14: Atomic, Molecular, and Nuclear Physics

Thus far we have mostly considered problems that can be solved exactly. This was not by accident. However, when discussing real atoms, molecules, and nuclei, we must often rely on numerical techniques. In this chapter we consider a few quantum-mechanical models that have varying success in describing (approximating) atoms, molecules, and nuclei.
