Abstract:
The kinetics of the interaction of Ag2+ with O2 is studied in the gas phase under multi-collision conditions at various temps. A new exptl. scheme is employed, which consists of an octopole ion trap of variable temp. inserted into a tandem quadrupole mass spectrometer. From the time evolution of the reactant and product mol. concns. at different temps. the corresponding reaction mechanism is extd. Surprisingly, the product Ag2O+ is detected, which is formed after mol. adsorption and dissocn. of...     »
