Recovery of broad hyperfine lines in electron spin-echo envelope modulation spectroscopy of disordered systems

A novel approach is proposed for the recording and processing of electron spin-echo envelope modulation spectra that is less sensitive to lineshape distortions of broad hyperfine lines. An unusually long pulse delay is employed in three-pulse stimulated-echo experiments. Observation is restricted to...

Description
Summary:A novel approach is proposed for the recording and processing of electron spin-echo envelope modulation spectra that is less sensitive to lineshape distortions of broad hyperfine lines. An unusually long pulse delay is employed in three-pulse stimulated-echo experiments. Observation is restricted to the so-called echo-modulation echo, and magnitude calculation is used to eliminate blind spots that distort conventional three-pulse echo-modulation spectra.
