Beyond the central-field approximation -- 5.6. Selection rules -- 5.7. The action of an external magnetic fieldpart III. Molecular physics. 6. Molecules : general features -- 6.1. What is a molecule? -- 6.2. The Born-Oppenheimer approximation -- 6.3. Molecular bonding7. Molecular vibrations and rotations -- 7.1. Molecular motions in diatomic molecules -- 7.2. Rayleigh and Raman scattering -- 7.3. Nuclear motions in polyatomic molecules8. Electronic structure of molecules -- 8.1. Problem definition -- 8.2. Molecular orbitals -- 8.3. Electronic configurations -- 8.4. Electronic transitions : the Franck-Condon principlepart IV. Concluding remarks. 9. What is missing in this 'primer'part V. Appendices. A. The formal solution of the Schr?odinger equation -- B. The spin-orbit interaction energy in hydrogenic atoms -- C. The hyperfine structure in hydrogenic atoms -- D. The 'minimal coupling' scheme -- E. Screening effects in He atom -- F. The Thomas-Fermi method -- G. The formal proof of the Born-Oppenheimer approximation -- H. The one-dimensional quantum harmonic oscillator.This book introduces the fundamental quantum physics of atoms and molecules. Divided into three parts, the first provides a historical perspective leading to the contemporary view of atomic and molecular physics, outlining the principles of non-relativistic quantum mechanics. The second part covers the physical description of atoms and their interaction with radiation, whilst the third part deals with molecular physics.Undergraduates on physics, materials science, chemistry and engineering courses.Also available in print.Mode of access: World Wide Web.System requirements: Adobe Acrobat Reader, EPUB reader, or Kindle reader.Luciano Colombo is a full professor of theoretical condensed matter physics at the University of Cagliari (I) and fellow of the 'Istituto Lombardo - Accademia di Scienze e Lettere' (Milano, I). He has been doing theoretical and computational research on materials physics for more than 30 years, publishing 250+ scientific papers and leading several research projects.Title from PDF title page (viewed on October 7, 2019).
