This book is excellent for a 1st year graduate course on Atomic and Molecular physics. The initial sections cover QM in as good and concise a manner as I’ve ever seen. The coverage of perturbation theory is also very clear. After that the book concentrates on Atomic and Molecular topics like fine structure, Hyperfine strucutre, Hartree-Fock, and a very nice section on Atomic collision physics. It’s truly regrettable that this book is out of print.
