Abstract We demonstrate anion mass spectrometry using the Hefei synchrotron radiation source to investigate the ion-pair dissociation processes of molecules. The efficiency curve of the O- anionic product via ion-pair dissociations of CO2 is recorded with tunable extreme vacuum ultraviolet photons (energy: 19.70-22.24eV) and compared with the spectrum available in the literature. The possible dynamics of CO2+hv →CO++O- in this energy range is discussed.
