O4 = TETRAOXYGEN (OXOZONE)
The tetraoxygen molecule (O4), also called oxozone, was first predicted in 1924 by Gilbert N. Lewis, who proposed it as an explanation for the failure of liquid oxygen to obey Curie’s law. Today it seems Lewis was off, but not by much: computer simulations indicate that although there are no stable O4 molecules in liquid oxygen, O2 molecules do tend to associate in pairs with antiparallel spins, forming transient O4 units (isn’t it the best definition of coworking???).
For us, the best explanation of O4 is that it is a possible rocket propellant!
There is another, more down to Earth story behind the name – as a reference to the name of the building we were established in March 2015 – Olivia Four.
