  text: We study a polar molecule immersed in a superfluid environment, such as a
    helium nanodroplet or a Bose–Einstein condensate, in the presence of a strong
    electrostatic field. We show that coupling of the molecular pendular motion, induced
    by the field, to the fluctuating bath leads to formation of pendulons—spherical
    harmonic librators dressed by a field of many-particle excitations. We study the
    behavior of the pendulon in a broad range of molecule–bath and molecule–field
    interaction strengths, and reveal that its spectrum features a series of instabilities
    which are absent in the field-free case of the angulon quasiparticle. Furthermore,
    we show that an external field allows to fine-tune the positions of these instabilities
    in the molecular rotational spectrum. This opens the door to detailed experimental
    studies of redistribution of orbital angular momentum in many-particle systems.
