A First Look for Molecules between 103 and 133 MHz using the Murchison
  Widefield Array
  We detail and present results from a pilot study to assess the feasibility of
detecting molecular lines at low radio frequencies. We observed a 400 square
degree region centred on the Galactic Centre with the Murchison Widefield Array
(MWA) between 103 and 133\,MHz targeting 28 known molecular species that have
significant transitions. The results of this survey yield tentative detections
of nitric oxide (NO) and the mercapto radical (SH). Both of these molecules
appear to be associated with evolved stars.
