未识别的红外发射带：多环芳烃或MAONs？
Unidentified Infrared Emission bands: PAHs or MAONs?
摘要：
我们认为，未识别的红外发射（UIE）带的载体是一个无定形的碳质固体与混合的芳香族/脂肪族结构，而不是自由飞行的多环芳烃（PAH）分子。通过光谱拟合的天文光谱的UIE波段，我们表明，大量的能量是由脂肪族成分，这意味着脂肪族基团的化学结构的重要组成部分。赞成的无定形，固态结构，而不是气相分子作为载体的UIE的参数也被提出。
英文摘要：
We suggest that the carrier of the unidentified infrared emission (UIE) bands is an amorphous carbonaceous solid with mixed aromatic/aliphatic structures, rather than free-flying polycyclic aromatic hydrocarbon (PAH) molecules. Through spectral fittings of the astronomical spectra of the UIE bands, we show that a significant amount of the energy is emitted by the aliphatic component, implying that aliphatic groups are an essential part of the chemical structure. Arguments in favor of an amorphous, solid-state structure rather than a gas-phase molecule as a carrier of the UIE are also presented.
