The method is applied to the calculation of the coupled translation-rotation eigenstates of H2 in water clathrate. %G English %L hal-01580148 %U https://hal.science/hal-01580148 %~ IN2P3 %~ CNRS %~ UNIV-PSUD %~ LUPM %~ INC-CNRS %~ UNIV-PARIS-SACLAY %~ UNIV-PSUD-SACLAY %~ UNIV-MONTPELLIER %~ LUPM_AS %~ TEST-HALCNRS %~ INSTITUT-SCIENCES-LUMIERE %~ UM-2015-2021 %~ TEST2-HALCNRS %~ ICPO
