Rovibrational overtone and combination bands of the HCNH＋ ion
Spectra of vibrational overtone and combination bands from vibrational ground state of were measured using an action spectroscopy technique with active background suppression in a cryogenic 22 pole radio frequency ion trap apparatus. Spectroscopic constants for the upper vibrational levels of the transitions were determined with vibrational band origins being 6846.77981(90) cm<sup>-1</sup> (2ν<sub>1</sub>, NH stretch), 6640.47624(43) cm<sup>-1</sup> (ν<sub>1</sub>+ν<sub>2</sub>), 6282.03578(63) cm<sup>-1</sup> (2ν<sub>2</sub>, CH stretch), and 6588.4894(20) cm<sup>-1</sup> (ν<sub>2</sub>+ν<sub>3</sub>+2ν<sub>5</sub><sup>0</sup>). State of the art ab initio VCI calculations up to 10<sup>4</sup>cm<sup>-1</sup> complement the experimental data.
