BOOK REVIEWS section on spertnrsropic methcrls disrusses rrlnrepts such rn rcsdution, l~andwirlth and responsr time, and the prinriples n i operation of mdiofreqoenry and rq~tiral spectrometers. The serrmd mnirrr improvement is that the section on elertronirs in the fifth edition has heen more than douhled in this revisirm. 4 r rireuit theory is treated using rompler algebra, and there are disrnssims r l f semirondurtor devices, noise phenotnena, and auseful raverage of assartetl elertrrmic circuits for power supplies, phasc ~ensit,ive detertors, pulse circuits, a n d elprtrrmir measurements. I t is the feeling of this reviewer that the new sections on electronics, neressnry fur most physical chemical research work, and molecular structure and spectra help t o meet serious defirienries in the previous edition and introduce the student tu a.ork which has ocrupied n l ~ r g ecore and physical chemistry in the last, twenty years.
