Physical Chemistry is designed specifically for chemistry students at both undergraduate and graduate levels. It develops the fundamentals of physical chemistry from the simple to the more complex, from atomic and molecular structure to properties of condensed matter, then to statistical and thermo-dynamic properties of systems in equilibrium, and then to transport phenomena and chemical reaction processes.
