An ESR study of single crystals KAsF6, γ irradiated and observed at 77°K, has been made. A three-fluorine center similar to the Vt center, F32−, identified, principal components directions for g tensor, fluorine hyperfine interaction tensors, have obtained. The is nonlinear with bond angle F–F–F = 150° ± 3°, odd-electron density being larger on central atom smaller two equivalent end atoms radical. INDO calculations suggest that it a σ-type radical unpaired spin distributed in orbitals lying plane three atoms.
