Abstract

The use of a laser‐desorption mass spectrometer to examine a coal liquefaction extract known to contain high‐molecular‐mass material (from size‐exclusion chromatography) has shown the presence of components of molecular mass in excess of 104Da for the first time. The molecules detected differ from each other in molecular mass by a few hundred or a few thousand Da. These preliminary results indicate that the basic coal‐structure molecules probably consist of aromatic clusters on a chin, in reasonable agreement with current theories of coal structure.
