The recent influx of high-quality infrared spectroscopic data has prompted an extensive reassessment of various laboratory models in comparison with the observed UIBs (Unidentified Infrared Bands). As a result, significant modifications were brought to the original paradigms. The focus here is on the correction of the coal model, characterized by: 1) a shift towards less aromatic materials of the same family (kerogens; the composition, structure and IR spectrum of these materials are… Expand
