This graphic is a Potential Energy Surface Scan for 2,6-Pyridyne. The X-axis of this graph is the C-C bond (Å), and the scan itself looked at the C-C Bond distance from 1.35 Å to 2.35 Å, in steps of 0.05 Å, moving from the bicyclic to the monocyclic form. This system is interesting in that its spin state changes over the course of the scan
