The foundations of quantum mechanics (Section 11.3) of the Physical Chemistry textbook, introduces the idea that electrons must be considered as both a particle and as having wave characteristics. This concept is absolutely key to understanding quantum mechanics and yet is sometimes hard to get a handle on.

Chapters 1 to 6 of Physical Chemistry - Laidler, Meiser, Sanctuary


Includes multimedia that opens on relevant pages and allows the student to visualize many of the concepts by varying parameters and plotting different graphs. Things students often have difficulty with, such as isothermal, isobaric, isochoric and adiabatic process, are clearly visualized.

Physical Chemistry - Laidler, Meiser, Sanctuary
Physical Chemistry textbook
by Laidler, Meiser, Sanctuary


This popular Physical Chemistry text book is now available in electronic format. We have preserved much of the material of the former hard copy editions, making changes to improve understanding of the concepts in addition to including some of the recent discoveries in physical chemistry. Many chapters have new sections and the coverage of several chapters has been greatly expanded.
