High-temperature heating processes for coal-tar-derived pitch (pitch A), petroleum-derived pitch (pitch B), and hydrogenated petroleum-derived pitch (pitch C) have been studied by in-situ hightemperature '"C-NMR. Mesophase formation processes have been successfully monitored for all three kinds of p
