Puri Sharma Pathania Physical Chemistry pdf book free Download

Puri Sharma Pathania principles of Physical Chemistry Book pdf is now available free here if you are studying in college, university this book cover all ugc syllabus.

If you are preparing for exams like UPSC, JAM, NET, GATE, then this is one of the most recommended books for physical chemistry that you can use during your graduation. This book has been made simple and topic wise so that students do not face any difficulty in reading the book. The most important part of the book is the numerical part which helps a lot in clearing the related concept.

What is Physical Chemistry

it is the study of macroscopic and particulate phenomena in chemical systems with reference to intellectual principles and concepts such as force, time, energy, thermodynamics, quantum chemistry, analytical dynamics, statistical mechanics.

Physical chemistry, in contrast to chemical physics, is primarily (but not always) a macroscopic or super-molecular science, as most of the principles on which it was founded pertain to bulk rather than only molecular/atomic structure. (for example, chemical equilibria and colloids).

This subject is traditionally divided into three parts – structure, equilibrium, change, and we usually study it in this order.

This Puri Sharma Pathania Physical Chemistry is the new edition of this book which has explained this broad topic in a simple way to fulfill the need of undergraduate and postgraduate students of Chemistry in Indian Universities. Some new chapters have also been added in this new version. Many questions have been given with examples so that the concepts of the students can be clear.

The partition function dominates statistical thermodynamics even as the wavefunction is of paramount importance in quantum mechanics. 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.

The significant feature of this edition is that two new chapters have been added: Quantum mechanics is dealt with in three chapters, instead of the earlier two, and statistical thermodynamics is spread over two chapters. Some material has been shifted at several places within the chapters to maintain continuity and impart lucidity and simplicity to the treatment. Structure dominates science and chemistry is no exception. And quantum mechanics and spectroscopy are the chemist’s tools to deal adequately with structure. Complete quantum mechanical treatment of the hydrogen atom, with special emphasis on the detailed solution of the Schrödinger equation, has been given. The radial equation and the spherical harmonics have at last received the emphasis they really deserved. Also, the approximate methods for the wave mechanical treatment of many-electron atoms have been updated. The perturbation theory both non-degenerate and degenerate has been adequately dealt with and applied to the first excited state of hydrogen atom. Several other modern topics which were earlier written as .Appendices or Further information 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.
