| الوصف: | trans-HOCO was produced by 193-nm photolysis of acrylic acid C 2 H 3 CO 2 H, and its reactions were studied using the rotational-vibrational transitions of the ν 1 O-H stretch. The thermal reaction rate constants for the reactions with O 2 and NO show no isotope dependence (±10% uncertainty) and have the following values: 1.9 (±0.2)×10 -12 cm 3 molecule -1 s -1 for O 2 and 2.45 (±0.2)×10 -12 cm 3 molecule -1 s -1 for NO at 293±2 K. The lack of an H/D isotope dependence is interpreted in terms of complex formation and dissociation, a mechanism in which hydrogen transfer is not the rate-limiting process |
