摘要：
High-molecular-weight organic matter in five C2 carbonaceous chondrites (Y-791198, Y-74662, Y-793321, B-7904, and Murchison) and six C3 carbonaceous chondrites (Y-790992, Y-791717, Y-81020, ALH-77003, ALH-77307, and Allende) were investigated by Curie-point pyrolysis-gas chromatography/mass spectrometry. A novel molecular model constructed with a polycyclic aromatic core having substituents around it was proposed as a general structure for the organic matter on the basis of the results of the pyrolitic examinations along with other spectroscopic studies.
