Since HF is known as interstellar species, the protonated HF may exist with detectable abundance. Vibration-rotation spectra of H_2F^+ ν_1 and ν_3 bands were studied by infrared laser spectroscopy The ν_2 band and pure rotational spectra have not been reported. In this study, we report FTIR spectroscopy of H_2F^+ ν_1, ν_3 and ν_2 bands.
The ion was produced with hollow cathode discharge in F_2, He and H_2 mixture. A simultaneous analysis of FT data combined with laser spectroscopic data was curried out for ν_1 and ν_3 bands, to determine ground state molecular constants. Absorption lines in the ν_2 region were assigned by using the ground state combination differences. Determined molecular constants can be used to predict pure rotational transition frequencies.
