Notes
-PES of N2O expressed as sum of pairwise and many-body potentials 
-Mixed-exponential-Gaussian (MEG) variables are applied
-This is a modified version of a potential originally published in 2016. 
 The difference between this surface and the published surface is that 
 the pairwise potentials of O2, NO and N2 are replaced with new ones that
 include dispersion terms, After this replacement, the least squares 
 fits of the four-body potential were redetermined. With these changes
 to the pairwise potentials, we have a unified set of potentials for 
 systems containing N2, O2, and NO that all use the same diatomic 
 potentials:
