Abstract

Infrared spectra have been obtained for (CN)₂CNN in the solid state and isolated in inert matrices. The vibrational analysis has been performed on the basis of C_2v symmetry and correlated with the spectra of a number of related molecules. Photolysis of matrix isolated (CN)₂CNN yields sufficient :C(CN)₂ [dicyanomethylene], stabilized in situ, to permit observation of the infrared spectrum. The observed bands are consistent with the predictions of a vibrational analysis which assumes a linear structure (D_∞h) for the diradical and utilizes force constants transferred from other molecules.
