Lasers in Chemistry (eBook, PDF)

• Format: PDF

Produktbeschreibung

Laser application in chemistry and related fields is an area growing at rapid pace in line with new developments in laser technology. The fields of application range from fundamental chemical research to sophisticated analytical methods in chemical and biotechnological industry and in environmental chemistry. This book shows, with detail, the breath of applications of lasers in chemistry, with particular reference to analytical and research applications. D.L. Andrews presents the subject matter at a level amenable to the general chemist, the novice and the practising specialists as well. The 3rd edition of this successful book has been completely revised and updated.
