Abstract
The homolytic bond dissociation energies of ZnO and ZnO^+ have been determined by using guided ion‐beam mass spectrometry to measure the kinetic‐energy dependence of the endothermic reactions of Zn^+ with nitrogen dioxide. The data are interpreted to yield the bond energy for ZnO, D^0_0=1.61±0.04 eV, a value considerably lower than previous experimental values, but in much better agreement with theoretical calculations. We also obtain D^0_0(ZnO^+)=1.67±0.05 eV, in good agreement with previous results. Other thermochemistry derived in this study is D^0_0(Zn^+–NO)=0.79±0.10 eV and the ionization energies, IE(ZnO)=9.34±0.02 eV and IE(NO_2)=9.57±0.04 eV.
