*1. Atkins’ Physical Chemistry:*The book has been written by Peter Atkins and Julio de Paula. The text has been enhanced with additional learning features and maths support and has been radically restructured into short focused topics.NEW TO THIS EDITION:

- Significant reorganization of the material within each chapter into discrete ‘topics’ makes the text more readable for students and more flexible for instructors.
- Expanded maths support includes new “Chemist’s toolkits” which provide students with succinct reminders of mathematical concepts and techniques.
- Three questions at the beginning of each topic engage and focus the attention of the reader: “ Why do you need to know this material?”, “What is the key idea?”, and “What do you need to know already?”
- New checklists of key concepts at the end of each topic reinforce the main take-home messages for each section.

** 2.** *Physical Chemistry:*

This book has been written by Ira N. Levine. This book is for the standard undergraduate course in physical chemistry. The book gives careful definitions and explanations of concepts, full details of most derivations, and reviews of relevant topics in mathematics and physics. Each chapter has a summary of the key points. The summaries list the specific kinds of calculations that students are expected to learn how to do. A substantial number of worked-out examples are included. Most examples are followed by an exercise with the answer given, to allow students to test their understanding. A wide variety of problems are included.

Many student errors in thermodynamics result from the use of equations in situations where they do not apply. To help prevent this, important thermodynamic equations have their conditions of applicability listed alongside the equations. Systematic listings of procedures for common kinds of processes are given. Detailed procedures are given for the use of a spreadsheet to solve such problems as fitting data to a polynomial, solving simultaneous equilibria, doing linear and nonlinear least-squares fits of data, using an equation of state to calculate vapor pressures and molar volumes of liquids and vapor in equilibrium, and computing a liquid-liquid phase diagram by minimization of G.

The book has been written by B.R.Puri, L.R.sharma and Madan S. Pathania. The book comprehensively covers the B.Sc and M.Sc Syllabi prescribed by UGC.

The significant features of this edition are that two new chapters have been added. Quantum mechanics is dealt with in 3 chapters and statistical thermodynamics is spread over 2 chapters. Some materials have been shifted at several places within the chapters to maintain continuity and impart lucidity and simplicity to the treatment. Complete quantum mechanical treatment of the hydrogen atom, with special emphasis on the detailed solution of the Schrodinger equation, has been given. The radiant equation and the spherical harmonics have at last received the emphasis they really deserved. Also, the approximate method for the wave mechanical treatment of many-electron atoms has been updated. Several other modern topics have been shifted to where they properly belong in the text. The treatment of angular momentum and atomic spectra is fairly comprehensive; the inessential details have been avoided. Several solved examples have been added. The chapter on statistical thermodynamics centres around the partition function derived from quantum mechanics. The new chapter on classical statistical mechanics builds on the concepts of phase space and Gibbsian ensembles and rederives results already known from conventional thermodynamics.
