| Resumo: | A study on the quantum dynamics of the hydrogen molecule embedded in the hollow cavity of a Single- walled Carbon Nanotube is presented, taking into account for the first time all six degrees of freedom of the confined molecule. A set of initial eigenstates of the trapped H2 molecule are propagated for 500 fs using the State Average Multiconfigurational Time-dependent Hartree approach. An initial linear momentum is added to the hydrogen molecule in order to mimic high temperature behavior, forming an angle of 0° and 45° with respect to the nanotube's axis; an additional propagation is carried out with- out adding any extra momentum. The wave packet dynamics are analyzed using projections and overlap functions in the appropriate degrees of freedom. The study reveals little correlation between the trans- lation of the confined molecule along the nanotube and the remaining degrees of freedom. |
