Abstract：Fourier transform infrared spectroscopy (FTIR) was applied to the study of the stress effect of compositions of macromolecular structure in tectonically deformed coals.The results showed that in different kinds of tectonically deformed coals, the absorption band of aromatic structure, aliphatic structure and oxygen functional groups nearly consistent in the peak wave number，but the intensity of the peak is different which is justly influenced by different deformation degree and deformation mechanism of tectonically deformed coals under tectonic stress.In the metamorphic and deformed environments of the low，middle and high coal rank, for tectonically deformed coals, with the increasing stress, hydrogen-enriched degree and oxygen-enriched degree decrease, while the degree of ring condensation increases.But there are differences in the change of compositions contents of macromolecular structure.This might indicate that the FTIR could be used in the stress effect of compositions of macromolecular structure in tectonically deformed coals.
