Constructing Potential Energy Surfaces for Polyatomic Systems: Recent Progress and New Problems

<table>Potential energy (b) and vibrational ground-state energy (a) along the reaction path of the H + NH<sub>3</sub> → H<sub>2</sub> + NH<sub>2</sub> reaction computed using the EC-2009 (solid lines) and MC (dashed lines) surfaces. The zero of energy is set to the equilibrium potential energy of the reactants.</table>
