The Temperature-Dependence of Rapid Low Temperature Reactions: Experiment, Understanding and Prediction. Smith, I., W., M., Sage, A., M., Donahue, N., M., Herbst, E., & Park, I., H. Faraday Discuss., 133:137-156, 2006. Website abstract bibtex Despite the success of the CRESU (Cinetique de Reaction en Ecoulement
Supersonique Uniforme) method in measuring rate coefficients for neutral--
neutral reactions of radicals down close to the very low temperatures
prevalent in dense interstellar clouds (ISCs), there are still many reactions
of potential importance in the chemistry of these objects for which there
have been no measurements of low temperature rate coefficients. One
important class of reactions is that between atomic and molecular free
radicals and unsaturated hydrocarbons; that is, alkynes and alkenes. Based
on semi-empirical arguments and correlations of `room temperature' rate
coefficients, k(298 K), for reactions of this type with the difference between
the ionisation energy of the alkyne/alkene and the electron affinity of the
radical, we suggest which reactions between the radicals, C(3P), O(3P),
N(4S), CH, C2H and CN, and carbon chain molecules (Cn) and
cyanopolyynes (HC2nCN and NCC2nCN) are likely to be fast at the
temperature of dense ISCs. These reactions and rate coefficients have been
incorporated into a purely gas-phase model (osu2005) of ISC chemistry.
The results of these calculations are presented and discussed.
