In 1927, Ira Sprague Bowen published the current explanation identifying their source as doubly ionized oxygen. [1] Other transitions include the forbidden 88.4 μm and 51.8 μm transitions in the far infrared region. [2] Permitted lines of O III lie in the middle ultraviolet band and are hence inaccessible to terrestrial astronomy.
Hydrogen, nitrogen, oxygen and chlorine are cheapest by volume at atmospheric pressure. When there is no public data on the element in its pure form, price of a compound is used, per mass of element contained. This implicitly puts the value of compounds' other constituents, and the cost of extraction of the element, at zero.

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 ...
Doubly ionized oxygen (O 2+), an ion; O(2), the 2-dimensional orthogonal group in group theory; O2, an EEG electrode site according to the 10–20 system;
The national average price for a gallon of regular unleaded gas is currently $3.40. Of the major metropolitan areas surveyed in Missouri, drivers in Columbia are paying the most at $3.28 on average.
Oxygen gas is the second most common component of the Earth's atmosphere, taking up 20.8% of its volume and 23.1% of its mass (some 10 15 tonnes). [19] [70] [d] Earth is unusual among the planets of the Solar System in having such a high concentration of oxygen gas in its atmosphere: Mars (with 0.1% O 2 by volume) and Venus have much less. The O
Gas prices within the last 10 years highlight how volatile the market can be. When looking at historical data, gas prices were the same in 2011 as they were in 2023 — $3.52 per gallon.
