The (1,0), (1,1), (1,2) bands of the system B2Σu+ – X2Σg+ of the ion N2+ are obtained in a hollow cathode discharge. The high resolution spectrometric recording has permitted an analysis of the frequencies and of the relative intensities of the rotational lines. The molecular constants and the parameters ξ and η of the perturbation of the vibrational level ν = 1 of the B2Σu+ state by the level ν = 11 of the state A2Πu have been determined.

Two band systems attributed to the P2+ molecule have been excited in a hollow cathode discharge tube. The first of these is a 2Π—2Π band system lying in the region 3400–3850 Å. The lower state of this system probably is the ground state of the P2+ molecule. The second system is a 2Σ—2Σ system lying in the region 3900–4400 Å. High resolution spectra of both the band systems have been analyzed and the rotational and vibrational constants determined.
