Аннотация:The Fourier transform emission spectrum of XeH+ was observed in the infrared region of the spectrum. The 1–0 and 2–1 vibration–rotation bands for 132XeH+, 131XeH+, and 129XeH+ were recorded from a nickel hollow cathode discharge in xenon and hydrogen. Molecular constants, including Re=1.602 813(6) Å, Be=6.560 686(50), αe=0.186 739(14), ωe=2269.9674(11), and ωexe=41.328 30(34) cm−1 for 132XeH+, were extracted from the line positions. Our work represents the first high-resolution detection of XeH+.
