Aromaticity Archives

(A) Spectral variation of the benzene:CO mixture before and after photon exposure. The dark blue line corresponds to the IR spectra before photon exposure, and the lighter blue corresponds to the IR spectra of the benzene:CO ice after photon exposure. (B) Spectral variation of the main aromatic bands as a function of photon fluence, with lighter colors representing higher photon fluence. Different colors are used to identify benzene, toluene, and benzonitrile. Each ice was exposed to approximately the same photon fluence of ∼7 × 1017 photons cm−2 (Table 2). Unless explicitly indicated, all subpanels share the same axis scale. -- astro-ph.IM

The Survival Of Aromatic Molecules In Protoplanetary Disks

by Keith CowingOctober 16, 2025June 10, 2026

Aromaticity is a common chemical functionalities in bioactive molecules. In interstellar and circumstellar environments benzene and other small aromatics are considered the precursor for more complex prebiotic molecules and they […]
