    "abstract": "We present a nonrelativistic calculation of the rotation-vibration levels of\nthe molecular ions H2+, D2+ and HD+, relying on the diagonalization of the\nexact three-body Hamiltonian. The J=2 levels are obtained with a very high\naccuracy of 10^{-14} a.u. (for most levels) representing an improvement by five\norders of magnitude over previous calculations. The accuracy is also improved\nfor the J=1 levels of H2+ and D2+ with respect to earlier works. Moreover, we\nhave computed the sensitivities of the energy levels with respect to the mass\nratios, allowing these levels to be used for metrological purposes.",
