A combination of cross-polarization and magic-angle spinning techniques were used for characterizing two sets of coal macerals. Eight maceral samples in the first set were measured; two alginites, two sporinites, three vitrinites and one fusinite, all of Carboniferous and Permo-Carboniferous age. Results were previously reported, and are now compared with a set of six vitrinite macerals from the Lower Kittaning seam. The variation in functionality observed in the second set of macerals indicates that systematic changes do occur within a given coal seam which can be attributed to rank consideration. Further study is indicated. 7 figure, 3 tables.
