Název v původním jazyce

A selected ion flow tube study of the ion molecule association reactions of protonated (MH+), nitrosonated (MNO+) and dehydroxidated (M-OH)(+) carboxylic acids (M) with H2O

Popis výsledku v původním jazyce

A selected ion flow tube, SIFT, study has been carried out of the reactions of H3O+, NO+ and O-2(+center dot) with four carboxylic acids: formic acid, acetic acid, propionic acid and butyric acid. Ethanol was also included in order to provide data that could facilitate SIFT-MS analyses of formic acid in its presence. The product ion branching ratios of the primary reactions were obtained and compared with the already known values, thus improving the certainty of kinetic data for quantification of thesecompounds. The primary products of the H3O+ reactions, the protonated molecules MH+, and the primary products of the NO+ reactions, nitrosonated (MNO+) and dehydroxidated (M-OH)(+) molecules, are observed to react with the molecules of water by three body association. Original data were obtained for the kinetics of these cluster-forming reactions. The three body rate constant for the associations of MH+ with H2O in He have been determined in the units of 10(-27) cm(3) s(-1) for formic, a
