Abstract The thermodynamic properties of oxygen complexes of the negative ions of 1-fluoro-2,4-dinitrobenzene (FDNB), 1,5-difluoro-2,4-dinitrobenzene (DFDNB), and sulfur dioxide have been determined by measuring the temperature dependence of the pertinent ion ratios by using a mass spectrometer equipped with a63Ni atmospheric pressure ionization source. The values of -ΔH° and -ΔS°are SO 2 −(O2), 101 ± 2.1 kJ mole1 and 121 ± 3.8 J/K-mole; FDNB−(O2), 51.5 ±3.4 kJ mole−1 ± 9.2 J/K-mole; and DFDNB−(O2), 65.7 ± 0.4 kJ mole−2 and 110 ± 5.0 J/K-mole.
