Structure and thermodynamics of KO3 and KO3+
The KO3 and KO3+ species are both calculated to have C-2v diamond structures, with a trans planar geometry lying higher in energy. For the cation, the energy difference between these two structures is only similar to1 ~ mol(-1). We calculate binding energies of the two species and obtain values of 126 +/- 1 and 8 +/- 1 kcal mol(-1), for K+...03 and K+...O3, respectively. The adiabatic ionization energy is determined as 7.0 +/- 1 eV and DeltaH(f)(0 K) values of -17 +/- 2 and 149 +/- 2 kcal mol(-1) are obtained for KO3 and KO3+ respectively..

Abstract

The KO3 and KO3+ species are both calculated to have C-2v diamond structures, with a trans planar geometry lying higher in energy. For the cation, the energy difference between these two structures is only similar to1 ~ mol(-1). We calculate binding energies of the two species and obtain values of 126 +/- 1 and 8 +/- 1 kcal mol(-1), for K+...03 and K+...O3, respectively. The adiabatic ionization energy is determined as 7.0 +/- 1 eV and DeltaH(f)(0 K) values of -17 +/- 2 and 149 +/- 2 kcal mol(-1) are obtained for KO3 and KO3+ respectively..
