Abstract
Equations that allow evaluation of electron spin echo (ESE) decay for rigid samples are derived from a basic theoretical framework. The mechanisms of normal spectral and instantaneous spectral diffusion are investigated, and their effects on the decay signal for two-pulse and three-pulse ESE sequences are analyzed and shown by simulated patterns. The case of T1 samples, where the mechanism that affects spin dephasing results from coupling with the lattice, and the case of T2 samples, where spin dephasing results from a flip-flop mechanism, are examined. Part II considers the presence of motion. ©1997 John Wiley & Sons, Inc. Concepts Magn Reson 9: 403–430, 1997
