: Electronic spectra, Laser physics (Masers, Lasers, and Non-Linear Optics), and Hyperfine structure. Pragati Prakashan Critical Review Comprehensive
This is the heart of the text. The authors flawlessly explain the Hydrogen atom spectrum, including fine structure (spin-orbit coupling) and hyperfine structure. For the Helium atom, they dedicate significant space to the variation method and perturbation theory to explain electron-electron repulsion. Atomic And Molecular Physics By Gupta Kumar Sharma Pdf
