The CN + C2H6 hydrogen abstraction gas-phase reaction represents a ten-body polyatomic complex system with 24 degrees of freedom. To describe the nuclear motion an analytical full-dimensional potential energy surface, PES-2023, was developed as a combination of valence bond and molecular mechanics functions, and fitted to high level ab initio calculations at the CCSD(T)-F12/aug-cc-pVTZ level. As these functions are based on simple and physically intuitive ideas, stretching, bending, torsions, etc, they permit i) the transferability from previous and similar surfaces to a new one, and ii) the use of a reduced and selected number of ab initio calculations in the fitting process, which represents an important saving of computational time and an advantage with respect to other approaches. PES-2023 simulates the ab initio enthalpy of reaction, barrier height and stability of the complexes in the entrance and exit channels, describing the topology of the surface for the electronic ground-state, within the Born-Oppenheimer approximation. This agreement represents a first test of quality of the new surface.
