| Guided ion beam mass spectrometry is used to study the kinetic-energy dependence of the reactions of copper, silver and alkali metal ions (M +) with oxygen containing ligands. The collision induced dissociation (CID) results indicate that these metal ions interact differently, even though they all have a 1S ground electronic state. These results are consistent with ab initio or density functional theoretical results.; New thermokinetic methods are developed for association reactions. The kinetic energy dependences of the association reaction cross sections are investigated using statistical theories such as RRKM and phase space theory. The resulting bond dissociation energies (BDEs) for dimethoxyethane (DXE) with copper and alkali metal ions are compared and found to be consistent with those obtained by CID and theoretical studies. |
