FTIR OBSERVATION AND DFT STUDY OF CoC$_3$ TRAPPED IN SOLID Ar

Author Institution: Department of Physics and Astronomy, Texas Christian University, Fort Worth, TX 76129Fourier 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 CoC$_3$. The CoC$_3$ chain was produced by the dual laser ablation of carbon and cobalt rods, followed by trapping the products in solid Ar at $\sim$10 K. FTIR measurements of $^{13}$C isotopic shifts are in good agreement with DFT predictions using both the BPW91 and B3LYP functionals with a 6-311+G(3\textit{df}) basis set, confirming the assignment of the $\nu_1$($\sigma$) fundamental of linear CoC$_3$ at 1918.2 cm$^{-1}$
