Peter Atkins' "Physical Chemistry" is viewed as a decent resource among physical chemistry textbooks, though it faces criticism for its broad scope, attempting to cover thermodynamics, statistical mechanics, classical mechanics, and electromagnetism in a single volume. The book has undergone significant revisions, leading users to be cautious about which edition they reference. Notably, it includes many biochemical examples, aligning with contemporary advances in biochemistry, which some readers appreciate. However, the clarity of reasoning in Atkins' explanations is questioned, particularly in the quantum mechanics section, where some concepts are seen as inadequately rigorous. Comparisons are made to other texts, with preferences leaning towards works by Moelwyn-Hughes and Walter J. Moore for their clarity and structure. There is a suggestion that physical chemistry should be divided into separate classes for quantum chemistry and thermal science to enhance understanding, rather than being consolidated into one book.
