FTIR spectra have been obtained for NCCN, CNCN, and CNNC in solid argon at 4K. Irradiation of $C2N2$ via corona discharge was the source of CN radicals. Isotopic labeling was used to obtain spectra for the $\mathrm{<mrow\; data-mjx-texclass="ORD">13</mrow>}C2\mathrm{<mrow\; data-mjx-texclass="ORD">14</mrow>}N2$ and $\mathrm{<mrow\; data-mjx-texclass="ORD">12</mrow>}C2\mathrm{<mrow\; data-mjx-texclass="ORD">15</mrow>}N2$ isomers. The data obtained permit a normal coordinate treatment to be performed and a derivation of force constants to be $made.a$ These results are compared with earlier $work.b$ FT Raman work is currently in progress.
