Abstract : | Rcently straight-chain (n-propyl cyanide, n−C3H7CN) and branched-chain (i-propyl cyanide, i−C3H7CN) species are identified toward a star-forming region, Sgr B2(N2). These molecules could be the ancestors of biologically relevant prebiotic molecules. Here, we study the formation of some higher-order (C5H9N isomeric group) branched-chain molecules in a similar star-forming region. Quantum chemical calculations are carried out to determine realistic parameters (binding energy, enthalpy of formation, polarizability, dipole moment, etc.) for the Astrochemical modeling. These parameters are further implemented in our gas-grain chemical model to study the chemical evolution of these species. Finally, obtained abundances are compared with the other existing models. |
