✦ Synopsis

It is shown that in pulse EPR experiments, absolute-value spectra can be distorted because of the instrumental dead time to an extent that the interpretation of the spectral features becomes impossible. The mathematical background for the description of the distortions is given, and the far-reaching consequences of the effect are illustrated by model calculations. A cross-term averaging procedure is proposed to get rid of these distortions in two-, three-, and four-pulse electron spin echo envelope modulation experiments. The potential of cross-term averaging is demonstrated in two- and three-pulse experiments on a single crystal and a powder sample.
