| Abstract : | The rotational line survey recently revealed the presence of i-C3H7CN (i-PrCN)
and n-C3H7CN (n-PrCN) in 3-mm atmospheric window between 80 GHz to 111 GHz
towards the hot core region Sagittarius B2(N2) (Sgr B2(N2)) with the Atacama Large Millimeter/submillimeter Array (ALMA). This was the first astronomical detection of a largest branched noncyclic molecule. In this light, through computational methods, we have studied the rotational spectrum of sec-butyl cyanide (s-C4H9CN) within the
same frequency range towards the Galactic Center star-forming source Sgr B2(N2). We performed quantum chemical calculations for spectroscopic parameters of astrochemically relevant molecules, followed by their rotational spectrum simulations for ALMA band-2 (67-90 GHz) for probable detection of s-BuCN in Sgr-B2(N). The rotational spectrum of s-BuCN makes it a good candidate for future astronomical search towards the Sgr B2(N2). |
