Atomic and molecular physics is a vast and diverse field that encompasses a wide range of topics, including atomic structure, molecular structure, spectroscopy, and collisions. The field has its roots in the early 20th century, when scientists such as Niels Bohr and Erwin Schrödinger laid the foundation for our understanding of atomic and molecular physics.
