Abstract: |
Rate constants for four gas-phase reactions related to the formation of complex organic compounds in the interstellar medium were determined theoretically using the POLYRATE kinetics and Gaussian 09 electronic structure modeling programs. Variational transition state theory rate constants with multi-dimensional optimized tunneling corrections were determined at the M05-2X/6-311++G(d,p) level of theory, then compared to rate constants taken from the Kinetic Database for Astrochemistry (KIDA). For two of the reactions, tunneling effects were predicted to produce a sunstantial increase in the rate constant below 300 K. The primary models used in KIDA do not account for the effects of tunneling on rate constants, even though low temperature gas-phase reactions are an integral part of interstellar chemistry. Properly including these effects will be essential for developing accurate models of the chemistry occurring in the interstellar medium. |
