Structure and Dynamics of Macromolecules: Absorption and Fluorescence Studies is clearly written and contains invaluable examples, coupled with illustrations that demonstrate a comprehensible analysis and presentation of the data. This book offers practical information on the fundamentals of absorption and fluorescence, showing that it is possible to interpret the same result in different ways. It is an asset to students, professors and researchers wishing to discover or use absorption and fluorescence spectroscopy, and to scientists working on the structure and dynamics of macromolecules.

Key Features

* Offers concise information on the fundamentals of absorption and fluorescence * Critically reviews examples taken from previously published literature * Highly illustrated, it is suitable for academic and institutional libraries and government laboratories


Academic and institutional libraries, government laboratories and scientists working in absorption and fluorescence spectroscopy, and on the structure and dynamics of macromolecules
