Detection of the Polycyclic Aromatic Hydrocarbon Phenalene (CH) in the Very Low Luminosity Object (VeLLO) MC27/L1521F
Gabi Wenzel, Thomas H. Speak, Ci Xue +12
To date, 14 polycyclic aromatic hydrocarbons (PAHs) ranging in size from two to seven (including five- and six-membered) carbon rings have been detected in the starless dense core…
The impact of hydrogen atom tunneling on aromatic chemistry in TMC-1
Reace H. J. Willis, Thomas H. Speak, Alex N. Byrne +2
Hydrogen atom tunneling likely plays a substantial role in the gas-phase chemistry of astrochemical environments. To determine the potential effect that it has on the chemical mode…
Rotational Spectra and Search for Aromatic Imines: 9-Iminofluorene and Benzophenone imine
Huanyu Ren, D. Archie Stewart, Gabi Wenzel +4
Interstellar detections of several cyano derivatives of large polycyclic aromatic hydrocarbons (PAHs) have now been achieved, enabled by accurate laboratory measurements of their m…
Discovery of the 7-ring PAH Cyanocoronene (CHCN) in GOTHAM Observations of TMC-1
Gabi Wenzel, Siyuan Gong, Ci Xue +18
We present the synthesis and laboratory rotational spectroscopy of the 7-ring polycyclic aromatic hydrocarbon (PAH) cyanocoronene (CHCN) using a laser-ablation assist…
