Abstract

Consideration of Si's cosmic abundance leads to the expectation that the related molecule SiH may be detected in extraterrestrial sources. A tabulation is presented of frequencies, wavelengths, and line strengths for SiH molecule transitions at microwave and far-IR wavelengths, on the basis of an analysis of its laser magnetic resonance spectrum. It is hoped that the frequencies presented will be useful to both laboratory spectroscopists and astrophysicists.
