Physical Chemistry for the Chemical Sciences isintendedforuseinaone-yearintro-
ductorycourseinphysicalchemistrythatistypicallyofferedatthejuniorlevel(the
third year in a college or university program). Students in the course will have taken
general chemistry and introductory organic chemistry. In writing this book, our aim is
to present the standard topics at the appropriate level with emphasis on readability and
clarity.Whilemathematicaltreatmentofmanytopicsisnecessary,wehaveprovided
a physical picture wherever possible for understanding the concepts. Only the basic
skills of differential and integral calculus are required for working with the equations.
The limited number of integral equations needed to solve the end-of-chapter problems
may be readily accessed from handbooks of chemistry and physics or software such
as Mathematica.
The 20 chapters of the text can be divided into three parts. Chapters 1–9 cover
thermodynamics and related subjects. Quantum mechanics and molecular spectros-
copy are treated in Chapters 10–14. The last part (Chapters 15–20) describes chemi-
calkinetics,photochemistry,intermolecularforces,solidsandliquids,andstatistical
thermodynamics. We have chosen a traditional ordering of topics, starting with ther-
modynamics because of the accessibility of the concrete examples and the closeness
