[J. Chem. Phys. 129, 134306 (2008)] with the MultiConfiguration Time Dependent Hartree (MCTDH) method. The J = 0 − 2 rovibrational bound states calculations are done with the Block Improved Relaxation procedure of MCTDH and the subsequent assignment of the states is achieved by inspection of the wavefunctions' properties. The results of this work are found to be in close agreement with previous time independent calculations reported for this complex and therefore supports the use of the MCTDH approach for the rovibrational spectroscopic study of such weakly bound complexes. %G English %2 https://hal.science/hal-03063989/document %2 https://hal.science/hal-03063989/file/10.1016.j.cplett.2018.11.035.pdf %L hal-03063989 %U https://hal.science/hal-03063989 %~ IN2P3 %~ CNRS %~ LUPM %~ JYB-LAB %~ UNIV-MONTPELLIER %~ QDN %~ LUPM_AS %~ TEST-HALCNRS %~ GS-CHIMIE %~ GS-PHYSIQUE %~ INSTITUT-SCIENCES-LUMIERE %~ UM-2015-2021
