Among the most likely producers of detectable radio line spectra are the light diatomic hydrides OH and CH ; somewhat less likely sources are the heavier hydrides SH , SiH , and ScH .

Among the most likely producers of detectable radio line spectra are the light diatomic hydrides OH and CH ; somewhat less likely sources are the heavier hydrides SH , SiH , and ScH .

Very small concentrations of these hydrides should be detectable ; in interstellar gas , concentrations as low as * * f molecules / * * f may be sufficient , as compared to the * * f hydrogen_atoms * * f required for detection of the 21 - cm line .

The first diatomic hydride investigated by the paramagnetic resonance method was the OH radical .
