Title: What allotropes of oxygen can exist at STP?
Post by: RD on 19/07/2016 03:01:03
I heard someone claim a quack-device produced O3 and O8 from O2 using high-voltage.

O3 (ozone (http://rationalwiki.org/wiki/Ozone_therapy)) I believe, but O8 at STP (https://en.wikipedia.org/wiki/Standard_conditions_for_temperature_and_pressure) ?

Singlet and triplet O2, and O3 are all I know of. I have never heard of O8, and would be highly surprised if such a molecule could be made in any appreciable quantity. S8 is a very common allotrope of sulfur, but that geometry would not be expected to work well for oxygen...

I've read O8 does occur ... https://en.wikipedia.org/wiki/Allotropes_of_oxygen
But I can't see how it could exist at room temperature and atmospheric pressure.
