Discovery of the 7-ring PAH Cyanocoronene (C24H11CN) in GOTHAM Observations of TMC-1
We present the synthesis and laboratory rotational spectroscopy of the 7-ring polycyclic aromatic hydrocarbon (PAH) cyanocoronene (C24H11CN) using a laser-ablation assisted cavity-enhanced Fourier transform microwave spectrometer.
