The perfluoroethyl and perfluoro-iso-propyl radicals show a planar distorted geometry, being the perfluoro-iso-propyl radical more planar (EPR analysis).

ABSTRACT
Perfluorodiacyl peroxides are an important class of perfluorinated peroxides. Thermal decompositions of selected perfluorinated peroxides have been analyzed in terms of stability of the radical products. In the temperature range of 0-90 °C, all these peroxides undergo first-order decomposition in diluted solutions. EPR analyses provide important information in order to determinate the structure of the oncoming perfluorinated radicals. Correlations between thermal stability and radical structures have been supposed.
