Abstract
After exposure of potassium azide to γ-rays at room temperature both N– 4 and N2– 3 have been identified by e.s.r. spectroscopy. The latter has not previously been detected in this material, but features previously assigned to pairs of N– 4 radicals are thought to be better identified with N2– 3. This radical is thought to be bent, with a bond angle close to 139°. The e.s.r. parameters are compared with those for other, isoelectronic radicals.
