Title: A narrow ESR signal and mesophase transformations in the heat treatment of coals and pitches

Abstract

The author discusses changes in the EPR spectrum when coal, pitch and its fractions are heated directly in the spectrometer resonator. It is shown that the high temperature maximum of EPR signals is determined to a significant extent by the narrow signal. This suggests that the narrow signal spectrum is related to the mesophase structures during the synthesis process.
