  The low-frequency sky may reveal some of the secrets yet to be discovered and
until recently, molecules had never been detected within interstellar clouds at
frequencies below 700MHz (Lovas, 2003) . Following the pilot survey towards the
Galactic Centre at 103--133MHz with the Murchison Widefield Array (Tremblay,
2017), we surveyed 400 degree squared centered on the Orion KL nebula from
99--170MHz. Orion is a nearby region of active star formation and known to be a
chemically rich environment. In this paper, we present tentative detections of
nitric oxide and its isotopologues, singularly deuterated formic acid,
molecular oxygen, and several unidentified transitions. The three identified
molecules are particularly interesting as laboratory experiments have suggested
these molecules are precursors to the formation of amines.
