摘要：

Kinetics of the (OH)-O-aEuro cent-initiated reactions of acetic acid and its deuterated isomers have been investigated performing simulation chamber experiments at T = 300 +/- 2 K. The following rate constant values have been obtained (+/- 1 sigma, in cm(3) molecule(-1) s(-1)): k (1)(CH3C(O)OH + (OH)-O-aEuro cent) = (6.3 +/- 0.9) x 10(-13), k (2)(CH3C(O)OD + (OH)-O-aEuro cent) = (1.5 +/- 0.3) x 10(-13), k (3)(CD3C(O)OH + (OH)-O-aEuro cent) = (6.3 +/- 0.9) x 10(-13), and k (4)(CD3C(O)OD + (OH)-O-aEuro cent) = (0.90 +/- 0.1) x 10(-13). This study presents the first data on k (2)(CH3C(O)OD + (OH)-O-aEuro cent). Glyoxylic acid has been detected among the products confirming the fate of the (CH2C)-C-aEuro cent(O)OH radical as suggested by recent theoretical studies.
