Detection of interstellar cyanamide (NH${}_2$CN) towards the hot molecular core G10.47+0.03

In the interstellar medium, the amide-type molecules play an important role in the formation of the prebiotic molecules in the hot molecular cores or high-mass star formation regions. The complex amide-related molecule cyanamide (NH${}_2$CN) is known as one of the rare interstellar molecule which has played a major role in the formation of urea (NH${}_2$CONH${}_2$). In this article, we presented the detection of the emission lines of cyanamide (NH${}_2$CN) towards the hot molecular core G10.47+0.03 between the frequency range 158.49$-$160.11 GHz using the Atacama Large Millimeter/submillimeter Array (ALMA) interferometric radio telescope. The estimated column density of the emission lines of NH${}_2$CN using the rotational diagram model was $N$(NH${}_2$CN) = (6.60$\pm$0.1)$\times$10${}^{15}$ cm${}^{-2}$ with rotational temperature ($T_{rot}$) = 201.2$\pm$3.3 K. The fractional abundance of NH${}_2$CN with respect to H${}_2$ towards G10.47+0.03 was $f$(NH${}_2$CN) = 5.076$\times$10${}^{-8}$. Additionally, we estimated the NH${}_2$CN/NH${}_2$CHO abundance ratio towards the G10.47+0.03 was 0.170, which was nearly similar with NH${}_2$CN/NH${}_2$CHO abundance ratio towards IRAS 16293$-$2422 B and Sgr B2 (M). We found that the observed abundance of NH${}_2$CN with respect to H${}_2$ towards G10.47+0.03 fairly agrees with the theoretical value predicted by Garrod (2013). We also discussed the possible formation and destruction pathways of NH${}_2$CN.
