Use of generalized exponential function to build three-dimensional reactive surfaces

Abstract

In this work, we introduce a new analytical form based on the q-exponential function to build three-dimensional reactive surfaces. The quality of this new function is tested by fitting the ab initio potential energy surface (PES) to the ground state Na+HF reaction. The thermal rate constant and reactive probabilities were determined considering this new PES. The obtained properties agree with those found for other PES available in literature.
