Abstract

Recent spectrographic observations by W. S. Adams at the Mount Wilson Observatory combined with identifications proposed by the writer have shown that several sharp lines of interstellar origin in the spectra of distant stars are due to transitions from the lowest energy states of the diatomic molecules CH and CN. Thus not only has it been shown that diatomic molecules exist in interstellar space but also the presence there of the hitherto undetected elements hydrogen, carbon, and nitrogen has been demonstrated.
