Astrochemical model to study the abundances of branched carbon-chain molecules in a hot molecular core with realistic binding energies [PDF]
, 2022 Straight-chain (normal-propyl cyanide, n - C3H7CN) and branched-chain (iso-propyl cyanide, i - C3H7CN) alkyl cyanides are recently identified in the massive star-forming regions (Sgr B2(N) and Orion). These branched-chain molecules indicate that the key amino acids (side-chain structures) may also be present in a similar region.

Rotational spectra of isotopic species of methyl cyanide, CH$_3$CN, in their $v_8 = 1$ excited vibrational states [PDF]
A&A 586, A17 (2016), 2015 Methyl cyanide is an important trace molecule in space, especially in star-forming regions where it is one of the more common molecules used to derive kinetic temperatures. We want to obtain accurate spectroscopic parameters of minor isotopologs of methyl cyanide in their lowest excited $v_8 = 1$ vibrational states to support astronomical observations,

Interstellar Isomers: The Importance of Bonding Energy Differences [PDF]
Astrophys.J.632:333-339,2005, 2005 We present strong detections of methyl cyanide, vinyl cyanide, ethyl cyanide and cyanodiacetylene molecules with the Green Bank Telescope (GBT) toward the Sgr B2(N) molecular cloud. Attempts to detect the corresponding isocyanide isomers were only successful in the case of methyl isocyanide for its J(K)=1(0)-0(0) transition, which is the first ...

Ilmu Pertanian (Agricultural Science), 2020 Cyanides are deadly toxic substances commonly found in cassava root tuber. Higher content of cyanides causes bitter taste of the root tuber. Therefore, analysis of cyanide content has been used as one of criteria for bitterness in cassava. The substitute

The quest for complex molecules in space: Laboratory spectroscopy of n-butyl cyanide, n-C4H9CN, in the millimeter wave region and its astronomical search in Sagittarius B2(N) [PDF]
Astron. Astrophys. 541 (2012) A121, 2012 The saturated n-propyl cyanide was recently detected in Sagittarius B2(N). The next larger unbranched alkyl cyanide is n-butyl cyanide. We provide accurate rest frequency predictions beyond the millimeter wave range to search for this molecule in the Galactic center source Sagittarius B2(N) and facilitate its detection in space.

Exploring molecular complexity with ALMA (EMoCA): Simulations of branched carbon-chain chemistry in Sgr B2(N) [PDF]
A&A 601, A48 (2017), 2017 Using mm-wavelength data from ALMA, the EMoCA spectral line survey revealed the presence of both the straight-chain and branched forms of propyl cyanide (C$_3$H$_7$CN) toward the Galactic Center star-forming source Sgr B2(N2). This was the first interstellar detection of a branched aliphatic molecule.

77Se and 13C NMR Characterization of Selenium Cyanides
Molbank, 2022 Here, we describe a magnetic resonance spectroscopy characterization of selenium cyanide compounds, Se(CN)2, Se2(CN)2 and Se3(CN)2. Selenim-77 and carbon-13 nuclides were used to provide data of these species at room temperature.
