Professor Atkins is the author of the moment in physical chemistry and he has produced some cracking chemistry books in the past.
However users of this one should be aware that it has undergone several major revisions so should be careful which edition they refer to.
Many of the examples are biochemical, which is unusual in a physical chemistry book, but in keeping with the modern advances in biochemistry and very welcome.
On balance, I prefer the previous generation book from Oxford by Moelwyn-Hughes or the one by W Moore, both of which I would give outstanding to.
This I would only rate as good.
