Electronic and photoelectron spectroscopy provides extraordinarily detailed information on the properties of molecules. This book presents the basic principles and experimental techniques employed in electronic and photoelectron spectroscopy. A major feature is the extensive use of case studies to illustrate how spectra are assigned and how information can be extracted. The text is intended for advanced undergraduate and graduate students studying courses in spectroscopy. Describes the theory and experimental techniques behind electronic and photoelectron spectroscopy Extensive use of case studies allows the reader to follow the reasoning employed in the assignment of molecular spectra and how the information is extracted from the spectrum Describes spectroscopic techniques
