Abstract

Twenty vibration–rotation lines in the bending fundamental of HN₂⁺ have been detected by absorption spectroscopy using a tunable-diode laser. The ions were produced in a large hollow-cathode discharge in a mixture of hydrogen and nitrogen maintained at liquid-nitrogen temperature. Analysis of the spectrum provides an accurate determination of the ν₂ band origin and the major parameters describing the (01 ¹0) state of the ion.
