ΔrH° (kJ/mol) Method Reference Comment
331. ± 8.4TDEqVeljkovic, Neskovic, et al., 1991gas phase; Fluoride Affinity: 37.5 kcal/mol less than AlF3; value altered from reference due to conversion from electron convention to ion convention; B
328. ± 14.TDAsAleshina, Borshchevskii, et al., 1996gas phase; value altered from reference due to conversion from electron convention to ion convention; B
330. ± 40.TDEqPyatenko, Guasarov, et al., 1984gas phase; value altered from reference due to conversion from electron convention to ion convention; B
301. ± 21.IMRELarson and McMahon, 1985gas phase; These relative affinities are ca. 10 kcal/mol weaker than threshold values (see Wenthold and Squires, 1995) for donors greater than ca. 27 kcal/mol in free energy. This discrepancy has not yet been resolved, though the stronger value appears preferable.; B,M
385. ± 25.TherMallouk, Rosenthal, et al., 1984gas phase; Fluoride affinities from this method appear to be consistently about 10 kcal/mol too bound; B
393. ± 21.TherKrivtsov, Titova, et al., 1977gas phase; Halide affinities from this reference are too high. G3MP2B3 calculations indicate an dHaff ca. 46 kcal/mol; value altered from reference due to conversion from electron convention to ion convention; B
