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 a new method of 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.

Iodine (I) is used to seed clouds, detect and treat cancer, prevent infections, and protect people from radiation in the even of a nuclear accident. Most of the iodine found in nature is in seaweed. Pure iodine can also be obtained from natural brines. This book delves into the properties of the group 17 elements, also called the halogens, and the subatomic makeup of iodine. Readers discover the role of valence electrons, and the use of iodine in biology labs and in identifying types of bacteria. Iodine compounds are examined and their many uses explained. The book also includes a discussion of iodine deficiency around the world.

This volume is the newest release in the authoritative series issued by the National Academy of Sciences on dietary reference intakes (DRIs). This series provides recommended intakes, such as Recommended Dietary Allowances (RDAs), for use in planning nutritionally adequate diets for individuals based on age and gender. In addition, a new reference intake, the Tolerable Upper Intake Level (UL), has also been established to assist an individual in knowing how much is "too much" of a nutrient. Based on the Institute of Medicine's review of the scientific literature regarding dietary micronutrients, recommendations have been formulated regarding vitamins A and K, iron, iodine, chromium, copper, manganese, molybdenum, zinc, and other potentially beneficial trace elements such as boron to determine the roles, if any, they play in health. The book also: Reviews selected components of food that may influence the bioavailability of these compounds. Develops estimates of dietary intake of these compounds that are compatible with good nutrition throughout the life span and that may decrease risk of chronic disease where data indicate they play a role. Determines Tolerable Upper Intake levels for each nutrient reviewed where adequate scientific data are available in specific population subgroups. Identifies research needed to improve knowledge of the role of these micronutrients in human health. This book will be important to professionals in nutrition research and education.
