|Abstract : ||The Interstellar detection of the straight-chain (n-propyl cyanide) and branched chain (i-propyl cyanide) molecules towards the star-forming region, Sgr B2(N2) enables the search for other Complex Organic Molecules (COMs). These molecules are precursors of bilogically relevant prebiotic molecules. In this light, we consider iso-propyl cyanide and other higher order branched chain molecules to form 3- Pyrroline isomeric group. We predict new formation and destruction pathways which could lead to more insight into the formation and destruction schemes of complex organic alliphatic to aromatic molecules in space.
Quantum chemical calculations such as binding energy, enthalpy of formation, reaction enthalpy, activation barrier, dipole moments, polarizability and other spectroscopic information are presented assist to study the chemical evolution and examine the possibility of target molecule.
