Improved Potential Energy Surface of Ozone Constructed Using the Fitting by Permutationally Invariant Polynomial Function

Figure 5

Global view of the ozone PES in three dimensions using the isoenergy surface at 0.2‚ÄČeV and the internal hyperspherical coordinates . The threefold symmetry is clearly seen. Each covalent well (at the bottom) is connected to two dissociation channels (at the top) through the narrow transition states. See text for details.
