The second choice of the three logical possibilities above for diamagnetic oxyhemoglobin being found correct by experiment, is not surprising: singlet oxygen ( possibility # 1 ) and large separations of charge ( possibility # 3 ) are both unfavorably high-energy states.

# Archean: a period defined by the first crustal formations ( the Isua greenstone belt ) until the deposition of banded iron formations due to increasing atmospheric oxygen content.

# Absorption: oxygen, nitrogen and carbon dioxide can diffuse into the epidermis in small amounts ; some animals use their skin as their sole respiration organ ( in humans, the cells comprising the outermost 0. 25 – 0. 40 mm of the skin are " almost exclusively supplied by external oxygen ", although the " contribution to total respiration is negligible ")

# Reduction means the oxidation number some part of the mineral is reduced which occurs when oxygen is scarce.

# The combustion process occurs as the volatile products and some of the char reacts with oxygen to primarily form carbon dioxide and small amounts of carbon monoxide, which provides heat for the subsequent gasification reactions.

A leak was detected between the liquid oxygen dome and injector for the # 4 H-1 rocket engine ; while attempts were made to fix the problem, it was eventually decided to launch without replacing the engine.
