Corrections for the Dielectric Effect

Most theoretical interpretations of condensed phase IE s have depended heavily on spectroscopic measurements of ZPE shifts to define limits on parameter assignments (force constant shifts). It is therefore a matter of some importance to determine the magnitude of dielectric corrections to be applied to such shifts. Fortunately dielectric corrections are larger than typical spectroscopic uncertainties in phase frequency shifts only for very intense IR bands, and therefore dielectric corrections are very often unnecessary.

The broken line in Figure 2 shows that the steady rate of oxidation of 4.07M ethylbenzene in acetic acid, catalyzed by cobalt acetate, reaches a limiting rate of 2.2 X 10 r> mole liter"1 sec. 1 (after correcting for the dielectric effect (5,9), 1.8 X 10 5), which is in excellent agreement with the theoretical limiting rate of 1.85 X 10"r> mole liter 1 sec. 1 as calculated by 32(RH)2/2 6.
