Vibrational transitions of the ⁷LiH⁺ ion calculated without the Born-Oppenheimer approximation and with leading relativistic corrections

We recently presented very accurate calculations of the fundamental vibrational frequency of the ⁷LiH⁺ and ³He ⁴He⁺ ions [Stanke et al., Phys. Rev. A 79, 060501(R) (2009)] performed without the Born-Oppenheimer approximation and included leading relativistic corrections. The accuracy of those calculations was estimated to be of the order of 0.06 cm^-1. In the present work we extend the calculations to the remaining pure vibrational states of ⁷LiH⁺ and similarly accurate results are generated. They may lead to the experimental search for still unidentified lines corresponding to those transitions.
