Abstract
The GeF ion was generated in the hollow cathode discharge of $^{71}GeF$ mixed with He, More than 30 absorption lines belonging to the fundamental band were observed by infrared diode laser spectroscopy and identified for five Ge isotopes. The spectroscopic constants derived for the GeF species are $\omega = 815.60(12). \omega 3.223(62) B_{c} = 0.40212.14$, and $0 = 0.0025060 53 cm^{-1}$. The equilibrium bond length $l = 1.66549 29 $ was calculated from the equilibrium rotational constant. A sharp decrease of the signal intensity caused by the magnetic field also confirmed that the observed spectrum was due to a charged species. Based on the results by the infrared spectroscopy, four millimeterwave lines for the $J 9 - 8 - 12 - 11$ rotational transitions were observed for each Ge isotope. The millimeterwave spectrum was consistent with the infrared results and much improved the molecular constants.
