Summary:

About the Book: This edition of the book has been designed to meet the latest requirements of undergraduate students preparing for bachelors degree in physical sciences of Indian Universities. The author has been very careful in selecting the topics, laying their sequence and style of presentation to make it easier to understand intrigue concepts. A large number of solved problems are given in each unit. The sequence of units adopted for Volume I are: Unit I-Special Theory of Relativity; Unit II-Quantum Mechanics; Unit III-Statistical Mechanics; Unit IV-Atomic Spectra; and Unit V-Molecular Spectra of Diatomic Molecules. Contents: Unit-I: The Special Theory of Relativity Unit-II: Quantum of Mechanics Origin of Quantum Concepts Wave Nature of Material Particles Schrodinger Equation Potential Barrier Problems Eigen Values of L DEGREES2 and L DEGREESZ Axiomatic Formulation of Quantum Mechanics Particle in a Box Harmonic Oscillator Rigid Rotator Particle in a Central Force Field Unit-III: Statistical Mechanics Preliminary Concepts Phase Space Ensemble Formulation of Statistical Mechanics Distribution Functions Applications of Quantum Statistics Partition Function Application of Partition Function Unit-IV: Atomic Spectra Atomic Spectra-I Atomic Spectra-II Atomic Spectra-III Magneto-optic and Electro-optic Phenomena X-Rays and X-Ray Spectra Unit-V: Molecular Spectra of Diatomic Molecules Rotational Spectra of Diatomic Molecules Vibrational Spectra of Diatomic Molecules Vibration-Rotation Spectra of Diatomic Molecules Electronic Spectra of Diatomic Molecules Raman Spectra Lasers
