Notes:
Spectra of 14N+2–20Ne, 14N+2–22Ne, and 15N+2–20Ne have been recorded in the region of the B 2Σ+u←X 2Σ+g origin transition of N+2. Measurements are made by mass selecting cooled ionic complexes and photodissociating them whilst monitoring the N+2 fragment ion intensity as the laser wavelength is scanned. Various bands are assigned to transitions involving the stretching and bending motions of the Ne...Ne+2 bond with their structure and spacings consistent with transitions between quasilinear geometries in the X and the B states. Spectra of complexes with up to eight neon atoms attached to a 14N+2 core have also been measured. Evidence from shifts of the band origins and analysis of the vibrational frequencies of N+2–Ne2 and N+2–Ne3 suggest a structure where the Ne ligands are sited at one end of the N+2 chromophore.
