Hello Fellow CCL Members, I want to fit an IRC data points attached to a polynomial form to get a potential function which I intent to use in calculating WKB barrier penetration integral. I have tried several simple polynomials forms up to 5th order including some exponentials using Mathematica's NonLinearModelFit but non of them seem to work! Does any of you guys have an idea what kind of form I should be trying? Thanks Fred
