    Rev. Lett. 114, 203001 (2015)PRLTAO0031-900710.1103/PhysRevLett.114.203001] to
    study the rotational spectrum of a cyanide molecular anion immersed into Bose-Einstein
    condensates of rubidium and strontium. Based on ab initio potential energy surfaces,
    we provide a detailed study of the rotational Lamb shift and many-body-induced
    fine structure which arise due to dressing of molecular rotation by a field of
    phonon excitations. We demonstrate that the magnitude of these effects is large
    enough in order to be observed in modern experiments on cold molecular ions. Furthermore,
    we introduce a novel method to construct pseudopotentials starting from the ab
    initio potential energy surfaces, which provides a means to obtain effective coupling
    constants for low-energy polaron models.
