($NH_{2})_{2} C_{2}NCN$. One of the spectra is a broad line of width 8 G. The other spectra each show interaction of an unpaired electron with one proton and one $N^{14}$ nucleus. One radical, with $a_{H}$ = 29 G and $a_{N}$ = 16 G is a $\pi$-electron radical whereas the other, with $a_{H}$ = 72.5 G and $a_{N}$ = 6 G appears to be a $\pi$-electron radical. The origin of the radicals in relation to the atom positions in the undamaged dicyandiamide crystal will be discussed. en_US dc.format.extent 59923 bytes dc.format.mimetype image/jpeg dc.language.iso English en_US dc.publisher Ohio State University en_US dc.title ELECTRON SPIN RESONANCE SPECTRA OF RADICALS IN GAMMA IRRADIATED DICYANDIAMIDE en_US dc.type article en_US
