Description
The iron hydride cation (FeH+) is believed to be an abundant transition metal compound in the interstellar medium (ISM). Due to the lack of laboratory data, it has not been identified in spectral observations. We performed infrared multiple photon dissociation (IRMPD) spectroscopy of FeH+ tagged with two argon atoms. The Fe-H stretch in Ar2FeH+ is observed at 1854 cm-1, and two weaker combination bands appear around 2000 cm-1 and 2080 cm-1, respectively, in agreement with quantum chemical calculations. The Ar-Fe-Ar bending mode is populated at the temperature of the experiment, most likely causing the observed broadening of the Fe-H stretch.
