Dissociative Electron Attachment to 2,6- and 2,5-Dihydroxyacetophenone

详细

Two model humic compounds, 2,6- and 2,5-dihydroxyacetophenone, were investigated by negative ion mass spectrometry. Dissociative electron attachment cross-sections and negative ion autodetachment lifetimes were measured in the electron energy region 0–10 eV. Adiabatic electron affinities of the compounds under investigation were evaluated. The results obtained were rationalized using DFT B3LYP/6-31G+(d) quantum-chemical calculations.
