  Recent observations have shown that Nitrogen-bearing complex organic species
are present in large quantities in star-forming regions. Thus, investigating
the N-bearing species in a hot molecular core, such as G10.47+0.03, is crucial
to understanding the molecular complexity in star-forming regions. They also
allow us to investigate the chemical and physical processes that determine the
many phases during the structural and chemical evolution of the source in
star-forming regions. The aim of this study is to investigate the spatial
distribution and the chemical evolution states of N-bearing complex organic
molecules in the hot core G10.47+0.03. We used the ALMA archival data of the
hot molecular core G10.47+0.03. The extracted spectra were analyzed assuming
LTE. Furthermore, robust methods such as MCMC and rotational diagram methods
are implemented for molecules for which multiple transitions were identified to
constrain the temperature and column density. Finally, we used the Nautilus
gas-grain code to simulate the nitrogen chemistry in the hot molecular core. We
carried out both 0D and 1D simulations of the source and compared with
observational results. We report various transitions of nitrogen-bearing
species (NH2CN, HC3N, HC5N, C2H3CN, C2H5CN, and H2NCH2CN) together with some of
their isotopologues and isomers. Besides this, we also report the
identification of CH3CCH and one of its isotopologues. The emissions
originating from vinyl cyanide, ethyl cyanide, cyanoacetylene, and cyanamide
are compact, which could be explained by our astrochemical modeling. Our 0D
model shows that the chemistry of certain N-bearing molecules can be very
sensitive to initial local conditions such as density or dust temperature. In
our 1D model, simulated higher abundances of species such as HCN, HC3N, and
HC5N toward the inner shells of the source confirm the observational findings.
