Abstract

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.
