ResumoA quantum chemical exploration is reported on the interaction potential of H2O2 (the simplest example of a chiral molecule) with rare gases. This study is a continuation of previous experimental and theoretical works on similar important systems (H2O [1] and H2S [2]). For these systems, a basic motivation is the determination of the interactions to be used in classical and quantum simulations of molecular collisions, specifically those leading to chirality changes of possible relevance in the modelling of prebiotic phenomena[3]. Features of the internal dynamics by stretching, bending and torsional modes were compared with previous experimental and computational information, focusing on the energy and dipole moment profile upon variation of the dihedral angle [4]. The description based on the vectors either of the usual valence picture and of the orthogonal local representation were compared, demonstrating that the latter is to be privileged for molecular dynamics simulations since the torsion around the vector joining the centre of mass of the two OH radicals mimics accurately the adiabatic reaction path for chirality changing isomerisation, i.e. the torsional potential energy profile from the equilibrium through the barriers for the trans and cis configurations. These results lead to the representation of the interaction potentials by a four dimensional energy surfaces, involving three external coordinates and the dihedral angles. Expansions in terms of hyperspherical harmonics are provided of direct use for the quantum and classical simulation of the collision dynamics.
