  Spectroscopic methods allow to measure energy differences with unrivaled
precision. In the case of gravity resonance spectroscopy, energy differences of
different gravitational states are measured without recourse to the
electromagnetic interaction. This provides a very pure and background free look
at gravitation and topics related to the central problem of dark energy and
dark matter at short distances. In this article we analyse the effect of
additional dark energy scalar symmetron fields, a leading candidate for a
screened dark energy field, and place limits in a large volume of parameter
space.
