Rings and Energy

We report on the same figure the energy of a hypothetical crystalline polymorph, B2O3-O whose density is close to that of the glass (1.81 gcm ) at ambient conditions [61] interestingly it falls well on our data at / = 0. 

The origin of this stabilisation energy remains unclear [28, 157] it has been proposed that it includes electronic contributions such as r-bonding from p orbitals 

In any case, the system is eventually quenched in a low-density and low-energy structure. The next section intends to further explore the reason why.
