Abstract

The Carr–Purcell–Meiboom–Gill (CPMG) multipulse protocol is actively used in magnetic resonance to study decoherence processes. However, its use in electron paramagnetic resonance spectroscopy is often related to manifestations of unwanted contributions from other signals. In this study, expressions for the observed echo signals in the CPMG protocol are obtained in an explicit form, taking into account the superposition of other signals at the time of observation. Separating the contributions of different signals by modifying the CPMG protocol is experimentally demonstrated.
