Magnetic Isotope Effect in Radical Reactions: An Introduction [Paperback]

In the last two decades it was demonstrated that, in addition to masses and charges, magnetic moments of nuclei are able to influence remarkably chemical reactions. This book presents the physical background (both theoretical and experimental) of the magnetic isotope effects in radical reactions in solutions. Special attention has been paid to the quantitative interpretation of the available experimental data.This book will be useful for physicists, chemists and biologists employing the isotope effect in their investigations as well as for those involved in isotope separation and isotope enrichment projects. Additionally, the magnetic isotope effect appears to be important in geochemistry and cosmochemistry.The book can be recommended for postgraduates and senior undergraduate students.1 Introduction.- 1.1 Origin of magnetic isotope effect in radical reactions.- 1.2 Favourable conditions for magnetic isotope effect.- 1.3 Some specific features of magnetic isotope effect.- 1.4 What can be gained from magnetic isotope effect?.- 1.5 Basic steps in studying magnetic isotope effect.- 2 Main concepts of the theory of magnetic isotope effect.- 2.1 Macroscopic and microscopic parameters.- 2.2 Radical pairs.- 2.3 Multiplicity and reactivity of radical pairs.- 2.4 The hyperfine coupling.- 2.5 Singlet-triplet transitions in radical pairs induced by the hyperfine interaction.- 2.6 Manifestations of radical pair spin conservation rules in singlet-triplet mixing induced by the isotropic hyperfine coupling.- 2.7 Kinetic equations for radical pair recombination.- 3 Theoretical description of magnetic isotope effect in the Earths magnetic field.- 3.1 Radical pairs with one magnetic nucleus (isotropic hyperfine coupling).- 3.2 Radical pairs with magnetically equivalent nuclei (isotropic hyperfine coupling).- 3.3 Radical pairs with many magnetically non-equivalent nuclei (isotropic hyperfine coupling).- 3.4 Magnetic isotope effect induced by the anisotropic hyperfine interaction (parl&
