Unravelling the structure of monocyclic carbon ring cations using vibrational spectroscopy

Year: 2026

Type: article

Abstract: shows more substantial differences, indicating a departure from their common structure. Density functional theory calculations suggest these observations are largely due to changes to the bond length alternation of the polyynic species, however, the exact structures are challenging to model using these methods. The results provide new insights into the geometric structure of carbon cluster cations along with the requisite spectroscopic data to search for these species in astrophysical environments.
