Handbook of Electron Spin Resonance, Softcover reprint of the original 1st ed. 1999 Volume 2

In the first volume, Professors Poole and Farach provided one of the first definitive reference tools for this field. In this second volume, the authors present a comprehensive source for subfields of ESR not covered in the first volume, including: * Sensitivity * Field Swept versus Frequency Swept Spectra * Resonators * Line Shapes * Electron Spin Echo Envelope Modulation * Hamiltonian types and symmetries * ESR Imaging * High Magnetic Fields and High Frequencies. Written by recognized experts in the field, and intended for students and researchers, these handbooks bring together wide-ranging data from diverse disciplines within ESR, and then integrate it into a comprehesive and definitive resource. An invaluable reference for all those involved in ESR research.
