This book is very nice and helpful to start field theory, I have consulted it during my M.Sc and now have a personal copy. Thanks to flipkart and partners for fast and safe services. Good packaging.

It contains the Advance Concepts of Quantum Mechanics in details. I think best text for PG Level. If we go through this in UG is makes QM easy.

If you are going for an introductory computational chemistry book ... this is one of the primary tools you have to use ... very good book ...

good book
