From H2+ to the multidimensional potential of the intermolecular interaction ArHBr: A canonical approach Academic Article uri icon


  • 2015 Elsevier B.V. All rights reserved. A proof-of-concept for the accurate generation of multidimensional intermolecular interaction potentials is demonstrated. The basis for evaluating this application is the available very accurate 3-D morphed potential of ArHBr. Starting from the well-defined potential of the simplest molecule, the diatomic H2+, a recently developed 1-D canonical potential is used with selected 2-D polyatomic data to generate the adiabatic intermolecular interaction potential in ArHBr, with HBr in the vibrational ground state. This represents the first application of canonical transformations to a higher vibrationally dimensional molecular system, in this case, ArHBr. Results indicate intrinsic bonding characteristics inherent to both systems.
