Introduction
Atomic physics focuses on electrons bound to nuclei and the energy levels, transitions, and dynamics within isolated atoms. Molecular physics extends this to systems of two or more atoms, adding vibrational and rotational degrees of freedom, intermolecular forces, and chemical bonding. Advances in theory and experimental tools — lasers, spectroscopy, cold-atom traps, and synchrotron sources — have driven major progress over the past century. The textbook Atomic and Molecular Physics (often titled
Anharmonic Corrections – Perturbative (VPT2) or variational (VSCF/VCI). Dive into many-electron methods (Hartree–Fock, CI, DFT)
