AbstractA method proposed to assign the symmetry character of the rovibrational spectrum of trimers has been applied to the case of H3+. This system, much lighter than previously investigated rare gas three body molecules such as Ar or Ne, constitutes a challenging example to test the possible limitations of this approach. Calculation of the corresponding rovibrational spectra for J= 1 and rotational constants and the corresponding comparison with results from hyperspherical coordinates methods reveals that distorsion Coriolis coupling terms, not accounted for in the original method, play a significant role for some specific symmetry representations.
