Mass spectrum of oxygen

WebIn astronomy and atomic physics, doubly ionized oxygen is the ion O 2+ ( O III in spectroscopic notation ). Its emission forbidden lines in the visible spectrum fall primarily at the wavelength 500.7 nm, and secondarily at 495.9 nm. Before spectra of oxygen ions became known, these lines once led to a spurious identification of the substance as ...
