几个不同级别的澳大利亚煤，两个美国无烟煤，石墨和选择的多核芳烃进行了研究，通过激光烧蚀FT-MS。结果表明，通过掺杂样品与碱金属盐，加合离子观察到的多环烃模型化合物，而各种尺寸的碳原子团簇形成的石墨和煤。煤中形成大的正碳团簇的难易程度与多环缩合程度有明显的关系。这表明，该技术可能是有用的估计芳族晶格在更高级别的煤和石墨材料的有序。
Several different rank Australian coals, two American anthracites, graphite and a selection of polynuclear aromatic hydrocarbons have been studied by laser ablation FT-m.s.. It is shown that by doping the samples with alkali metal salts, adduct ions are observed for the polycyclic hydrocarbon model compounds, while a range of various size carbon clusters are formed from graphite and the coals. There is an apparent relationship between the ease of large positive carbon cluster formation from the coals and the degree of polycyclic ring condensation. This suggests that the technique may be useful for estimating the ordering of aromatic lattices in higher ranked coals and graphitic material.
