Carbon mono-oxide (CO)

Explanation:

Hydrogen exist with various molecules in space which includes carbon mono-oxide, hydroxide, ammonia, carbon (iv) oxide, silicon monoxide and other molecules. They combine in cold regions of space and exist as complex molecules. However hydrogen molecules do not emit radio energy. However CO molecules emit radio energy and hence are used to detect the presence of hydrogen.
