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.
