Abstract

The fundamental (SiH+)-Si-28 ion has been characterized in a collaborative work, utilizing a hollow-cathode discharge laser spectrometer and a cryogenic ion trap spectrometer. Twenty-three vibration-rotation transitions around 4.75 mu m have been detected with high accuracy. This has facilitated the first direct measurement of the pure rotational transition J = 1 <- 0 at 453056.3632(4). MHz in the trap spectrometer. The measured and accurately predicted transitions enable the search for this ion in space with IR and sub-mm telescopes.
