Benzonitrile (C6H5CN) has emerged as a key astrochemical molecule, yet the vibrational spectra of its ionic forms remain incomplete. In this work, we present first IR absorption mass-selected C6H5CN+ and C6H5CN- isolated in solid neon at 3 K. Distinct features both ions were identified through their differential response to UV photolysis comparison with theoretical predictions frequencies intensities. These results provide valuable spectroscopic benchmarks for identification benzonitrile space highlight effectiveness matrix-isolation techniques resolving structures transient molecular relevant astrochemistry.
