Tropospheric Reactions of H+(NH3)m(H2O)n with Pyridine and Picoline

摘要

Rate constants for the reactions of H+(NH3) sub m (H2O) sub n with pyridine and all three picolines have been measured for m + n 5. The rate constants were found to be large for all m and n studied. The reactions proceed by proton transfer, with an undetermined number of ligands transferred. Estimates of the rate constants at 300 K have been made for the reactions needed to derive pyridine and picoline concentrations in the atmosphere. Reprints, Hydrogen, Water, Ammonia. (mjm)
