Anharmonic Infrared Emission of Cyano-Substituted Polycyclic Aromatic Hydrocarbon Molecules: Cyanonaphthalenes as a Case Study
Tao Chen, Kaijun Li, Aigen Li
Recent detections of cyano-substituted polycyclic aromatic hydrocarbons (cyano-PAHs) highlight them as key tracers of nitrogen heterocycles in the interstellar medium (ISM). Howeve…
Infrared Emission of Polycyclic Aromatic Hydrocarbon Molecules in Titan: Cyanonaphthalenes
Li Zhou, Kaijun Li, Aigen Li +1
As the only moon in the solar system with a thick atmosphere, Titan is a compelling and enigmatic world containing a complex organic haze. Polycyclic aromatic hydrocarbon (PAH) mol…
Infrared Emission of Specific Polycyclic Aromatic Hydrocarbon Molecules: Indene
Kaijun Li, Aigen Li, Xuejuan Yang +1
Polycyclic aromatic hydrocarbon (PAH) molecules have long been suggested to be present in the interstellar medium (ISM). Nevertheless, despite their expected ubiquity and sustained…
Infrared Emission of Specific Polycyclic Aromatic Hydrocarbon Molecules: Cyanonaphthalenes
Kaijun Li, Aigen Li, Xuejuan Yang +1
The unidentified infrared emission (UIE) features at 3.3, 6.2, 7.7, 8.6, 11.3 and 12.7 micron are ubiquitously seen in a wide variety of astrophysical regions and commonly attribut…
