This is the first ever compendium of double photoionisation spectra, covering some 70 of the most important small and medium sized molecules and thus providing an essential starting point for studies of the consequences of ionisation by high energy photons in both terrestrial and astrophysical environments. It also provides a complete non-mathematical description of all the phenomena and pathways involved in molecular double photoionisation. Most spectra are presented with identification of the electronic states and leading orbital configurations. The technique of magnetic bottle time-of-flight electron spectroscopy, used for all the spectra, is fully explained and compared with other techniques. For each molecule, the book gives full references to relevant work by complementary techniques and to theoretical calculations.

Written in a clear non-mathematical style, this book is accessible to students as well as more experienced researchers. The authors have designed the layout for easy retrieval of any desired spectrum through the systematic organisation and ordering of the compounds and thorough indexing. As well as being a compendium of spectra, the book is a textbook covering all the known phenomenological aspects of molecular double photoionisation. The important phenomena are first mentioned in the introductory chapters, and are discussed in more detail in connection with the groups of molecules and individual cases where they are most relevant. The most useful spectra will be available in digital form for users.

About the Author:
John Eland, Emeritus Professor of Physical Chemistry and Fellow of Worcester College, University of Oxford, Raimund Feifel, Professor of Experimental and Molecular Physics, University of Gothenburg

John Eland studied chemistry at University College and in the Physical Chemistry Department of Oxford University. He then continued research in molecular physics in Germany (Freiburg), France (Paris, Orsay) and the USA (Argonne National Laboratory) before returning to Oxford, where he started as a University Lecturer and Fellow of Worcester. During his more than twenty years based in Oxford, he spent substantial periods as a visiting professor in Japan (Okazaki and Sendai), Paris and Uppsala, Sweden. He was elected to Fellowship of the Royal Society in 2006. Since formal retirement, he has continued active research in Oxford and as a guest professor in Uppsala and Gothenburg. His publications include a book on photoelectron spectroscopy and well over two hundred papers on physical and chemical topics, concentrated on molecular ions and ionisation.

Raimund Feifel received his basic physics training at the University of Konstanz in Germany, and his research training at Uppsala University in Sweden. He carried out postdoctoral research in physical chemistry at Oxford University before returning to Sweden, where he held a series of competitive research fellowships from the Swedish Research Council, followed by appointments as professor at Uppsala University and, most recently, at the University of Gothenburg. For almost twenty years he has worked in the field of electron spectroscopy of molecular systems in different states of charge and excitation, involving many collaborations at an international level (Sweden, USA, Japan, UK, Germany, France, Italy, Finland and Czech Republic). His list of publications comprises more than one hundred and sixty papers on photoionization of free atoms and molecules.
