Notes: 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, D00=1.61±0.04 eV, a value considerably lower than previous experimental values, but in much better agreement with theoretical calculations. We also obtain D00(ZnO+)=1.67±0.05 eV, in good agreement with previous results. Other thermochemistry derived in this study is D00(Zn+–NO)=0.79±0.10 eV and the ionization energies, IE(ZnO)=9.34±0.02 eV and IE(NO2)=9.57±0.04 eV.
