Description

International Series of Monographs in Natural Philosophy, Volume 33: Theory of Experiments in Paramagnetic Resonance discusses the technique for studying materials with unpaired electrons. This book is divided into four chapters. Chapter 1 provides a general introduction to examining matter through applying a magnetic field. The paramagnetic resonance line, such as the HF susceptibility as a function of certain parameters, is analyzed in the next chapter. Chapter 3 deals with the electronic signal that produces the HF susceptibility. The last chapter is devoted to the enhancement of the electronic signal above noise. This volume is beneficial to chemists and students interested in paramagnetic resonance.
