Exchange Effects in Alkali Ozonates

Resonance absorption has been observed in polycrystalline samples of potassium and cesium ozonate. The absorptions are characterized by nearly free electron spin $g$ values with line widths ranging from 26 to 49 oersteds. Analysis of line shapes based on the Anderson-Weiss model for exchange interaction between equivalent magnetic ions and calculations of line shape moment ratios based on the Van Vleck theory, strongly suggest exchange interaction narrowing. Values of exchange frequencies for potassium and cesium ozonate are estimated to be 6×${10}^{11}$ rad ${\sec }^{-1\mathrm{}}$ and 3×${10}^{11}$ rad ${\sec }^{-1\mathrm{}}$, respectively.
