Effects of ionizing radiation on cyanamide and dimethylcyanamide
Abstract
Irradiation of the pure title compounds and a range of dilute solid solutions produces a range of matrix-isolated radicals, identified by their EPR spectra. These include electron-loss centres, HNCN and (Me2NCN)+, and electron capture centres HNC(H)N˙– and Me2N˙. The former is a tautomer of the parent anion and the latter is formed by loss of CN–. In aqueous alkali glasses, the radical anion ˙N2CO3– is thought to be formed by addition of O˙– to CN2–2.
