THE SPECTRUM OF THE P2+ MOLECULE

Abstract

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.
