Rate Constant Determination in the Reaction of Gold ion with Carbonyl Using Single-Atom Chemistry in Gas Phase

气相单原子化学法测定金离子与羰基反应的速率常数

The reactions of single gold ion Au^(+)with CO and H_(2)O molecules in gas phase were studied by experiment and calculation.A reaction tube was designed under the steam of the laser sputtering position to destroy the supersonic molecular jet and enhance the collisions between the sputtered metal ions with gas molecules,ensuring the equilibrium reaction conditions.The ionic products were analyzed by a time-of-flight mass spectrometer.
