- Abstract
In the interstellar medium, the amide-type molecules play an important role in the formation of 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 a major role in the formation of urea (NH 2 CONH 2 ). In this paper, we presented the detection of the rotational emission lines of cyanamide (NH 2 CN) towards the hot molecular core G10.47 + 0.03 between the frequency range of 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 ± 0.1) × 10 15 cm - 2 with rotational temperature ( T rot) = 201.2 ± 3.3 K. The fractional abundance of NH 2 CN with respect to H 2 towards the G10.47 + 0.03 was f (NH 2 CN) = 5.076 × 10 - 8 . Additionally, the estimated 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 the IRAS 16293–2422 B and Sgr B2 (M). We found that the observed abundance of NH 2 CN with respect to H 2 towards the 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.
