Electron Paramagnetic Resonance

JOHN A. WEIL is Professor Emeritus of Chemistry and Physics at the University of Saskatchewan and an active international researcher in the field of EPR and NMR spectroscopy and theory. JAMES R. BOLTON is President of Bolton Photosciences, which provides specialty consulting services for the development and operation of ultraviolet (UV) technologies. He is Adjunct Professor in the Department of Civil and Environmental Engineering at the University of Alberta, and Professor Emeritus of Chemistry at the University of Western Ontario.

"Highly recommended to researchers seeking applications that would harness the potential of EPR spectroscopy to related fields of study. The authors are to be congratulated on producing a truly formidable EPR bible that lays claim once again to being the standard of work on the subject." (Journal of Chemical Education, January 2009)
