Fourier transform infrared (FTIR) and density functional theory (DFT) isotopic studies have been initiated on cobalt-carbon species and have resulted in the detection of linear CoC₃. The CoC₃ chain was produced by the dual laser ablation of carbon and cobalt rods, followed by trapping the products in solid Ar at 10 K. FTIR measurements of ¹³C isotopic shifts are in good agreement with DFT predictions using both the BPW91 and B3LYP functionals with a 6-311+G(3 df ) basis set, confirming the assignment of the ₁( ) fundamental of linear CoC₃ at 1918.2 cm^-1.
