Identification of pre-biotic molecules containing Peptide-like bond in a
  hot molecular core, G10.47+0.03
  After hydrogen, oxygen, and carbon, nitrogen is one of the most chemically
active species in the interstellar medium (ISM). Nitrogen bearing molecules
have great importance as they are actively involved in the formation of
biomolecules. Therefore, it is essential to look for nitrogen-bearing species
in various astrophysical sources, specifically around high-mass star-forming
regions where the evolutionary history is comparatively poorly understood. In
this paper, we report the observation of three potential pre-biotic molecules,
namely, isocyanic acid (HNCO), formamide (NH2CHO), and methyl isocyanate
(CH3NCO), which contain peptide-like bonds (-NH-C(=O)-) in a hot molecular
core, G10.47+0.03 (hereafter, G10). Along with the identification of these
three complex nitrogen-bearing species, we speculate their spatial distribution
in the source and discuss their possible formation pathways under such
conditions. The rotational diagram method under the LTE condition has been
employed to estimate the excitation temperature and the column density of the
observed species. Markov Chain Monte Carlo method was used to obtain the best
suited physical parameters of G10 as well as line properties of some species.
We also determined the hydrogen column density and the optical depth for
different continuum observed in various frequency ranges. Finally, based on
these observational results, we have constructed a chemical model to explain
the observational findings. We found that HNCO, NH2CHO, and CH3NCO are
chemically linked with each other.
