Here we show collision-induced luminescence spectra measured for collisions of the He+cations with thearomatic six-membered ring of the pyridine molecule (C5H5N). Distinct emission bands due to the CH(A2Δ→X2Πr;B2Σ+→X2Πr;C2Σ+→X2Πr), CN(B2Σ+→X2Σ+), C2(d3Πg→a3Πu), and NH(A3Π→X3Σ−) transitions, aswell as atomic H, He, and C lines have been observed. Apart from the He atoms, all the emitters arise from thefragmentation of the pyridine ring. The identification of the helium lines indicates a single electron transferreaction from the pyridine molecule to the He+cations. The products’intensities relative to the Hβintensityhave also been obtained and compared with the intensity ratios determined for He++ furan collisions.
