Beschreibung
This book presents experimental and theoretical spectroscopic studies performed over the last 25 years on the iodine molecule’s excited states and their perturbations. It is going to be of interest to researchers who study intra- and intermolecular perturbations in diatomic molecules and more complex systems.
The book offers a detailed treatment of the nonadiabatic perturbations of valence, ion pair and Rydberg states induced by intramolecular as well as intermolecular interactions in collisions or in weakly-bound complexes. It also provides an overview of current instrumentation and techniques as well as theoretical approaches describing intra- and intermolecular perturbations.
The authors are experts in the use of spectroscopy for the study of intrinsic and collision-induced perturbations in diatomic iodine. They introduced new methods of two- and three-step optical population of the iodine ion-pair states. The iodine molecule has 23 valence states correlating with three dissociation limits, 20 so-called ion-pair states, nestled in four tiers and a multitude of Rydberg states. All the states have different angular momenta, parities and very dense rovibronic levels. Moreover, perturbations caused by atomic or molecular partners lead to effective nonadiabatic transitions. For these reasons the authors propose this molecule as a model system for spectroscopic studies of intra- and intermolecular perturbations in other diatomic molecules.
Expounds the spectroscopy and underlying theory of a prototypical diatomic molecule Provides a useful paradigm to analyze processes that occur in other diatomic as well as polyatomic molecules Summarizes the progress of spectroscopic studies realized over the last 25 years Presents new data concerning intermolecular perturbations

“This will be a useful resource for researchers interested in the iodine molecule, its collisions and its vander Waals complexes. … this book provides an excellent snapshot of the current knowledge of the spectroscopy and perturbations of the iodine molecule, and should be regarded as such.” (Stephen H. Ashworth, Contemporary Physics, December 11, 2020)
