Abstract

The A²Σ⁺-X²Π electronic transition of the nitrous oxide cation, N₂O⁺, was measured via photodissociation spectroscopy in a cryogenic electrostatic ion storage ring. Rotationally resolved spectra of the N-O stretching vibrational sequence were obtained by detecting neutral N fragments produced via N₂O⁺ → NO⁺ + N predissociation channels. A new set of molecular constants was determined for the high-lying vibrational levels of the A²Σ⁺ state.
