Physics of Atoms and Molecules is a fundamental course being taught to graduate as well as postgraduate students of Physics, Chemistry, Biotechnology and Materials Science. Though a number of books are available on this topic, but here special care has been taken that a common student could understand the course without much efforts in an easily understandable manner. This book discusses about the Models for Atoms, One, Two and Several Valence Electron Atoms, Zeeman and Paschen-Back Effects in One and Two Valence Electron Atoms, Stark Effect, X-ray Spectra, Hyperfine Structure, Breath of Spectral Lines, Rotational Spectroscopy, Infrared Spectroscopy and Electronic Structure of Diatomic Molecules. For these topics, every part is explained with the help of simple exercises and by using simple language.

• • Subject is introduced in a very simple manner so that a common student could understand it • Each topic is explained with the help of simple exercises • Details of mathematical expressions are given in a manner so that the students could understand independently • Simple language, understandable to a common student, is used
