A Grotrian diagram of doubly ionized oxygen: forbidden transitions in the visible spectrum are shown in green. In astronomy and atomic physics, doubly ionized oxygen is the ion O 2+ (O III in spectroscopic notation).
They were shown as due to doubly ionized oxygen at extremely low density, [7] rather than the hypothetical nebulium. As Henry Norris Russell put it, "Nebulium has vanished into thin air." Nebulae are typically extremely rarefied, much less dense than the hardest vacuums produced on Earth. In these conditions, lines can form which are suppressed ...

Double ionization is a process of formation of doubly charged ions when laser radiation or charged particles like electrons [1], positrons [2] or heavy ions [3] are exerted on neutral atoms or molecules. Double ionization is usually less probable than single-electron ionization. Two types of double ionization are distinguished: sequential and ...
Molecular orbital diagram of dioxygen. Oxygen has a similar setup to H 2, but now we consider 2s and 2p orbitals. When creating the molecular orbitals from the p orbitals, the three atomic orbitals split into three molecular orbitals, a singly degenerate σ and a doubly degenerate π orbital.
The Trifid Nebula was the subject of an investigation by astronomers using the Hubble Space Telescope in 1997, using filters that isolate emission from hydrogen atoms, ionized sulfur atoms, and doubly ionized oxygen atoms. The images were combined into a false-color composite picture to suggest how the nebula might look to the eye.
