Nitric Oxide and other molecules: Molecular Modelling and Low
  FrequencyExploration using the Murchison Widefield Array
  We present new molecular modelling for 14NO and 15NO and a deep, blind
molecular line survey at low radio frequencies (99-129 MHz). This survey is the
third in a series completed with the Murchison Widefield Array (MWA), but in
comparison with the previous surveys, uses four times more data (17 hours vs. 4
hours) and is three times better in angular resolution (1' vs. 3'). The new
molecular modelling for nitric oxide and its main isotopologue has seven
transitions within the MWA frequency band (although we also present the higher
frequency transitions). Although we did not detect any new molecular lines at a
limit of 0.21 Jy beam^-1, this work is an important step in understanding the
data processing challenges for the future Square Kilometre Array (SKA) and
places solid limits on what is expected in the future of low-frequency surveys.
The modelling can be utilised for future searches of nitric oxide.
