Article abstract of DOI:10.1021/ja00350a006

The torsional motion was modeled by a potential representing a competition between bonding forces tending to stabilize the planar conformation and repulsive forces between oxygen atoms on different -NO//2 groups tending to destabilize it. The results suggest the motions of the -NO//2 groups are loosely coupled in a way such that one torsion angle tends to increase from the minimum energy point as the other decreases.
