A set of ยฎve coals have been electrochemically hydrogenated and changes to the chemical structure were monitored by elemental analysis and NMR. It was thought that the elemental analysis gave spurious results due to possible hydrogen trapping. The NMR clearly showed a decrease in aromatic material a
