Abstract: A brief account is given of the discovery of the astronomical maser and laser effects in OH radicals and in molecules of water (H₂O), carbon monoxide and dioxide (CO and CO₂), ammonia (NH₃), methyl alcohol (CH₃OH), formaldehyde (CH₂O), and silicon oxide (SiO). A detailed table is given of all the currently known molecular stimulated-emission lines.
