General Description

Cobalt chloride is a chemical compound composed of cobalt, chlorine, and water molecules. It is a pink solid at room temperature that turns blue when heated due to the release of water molecules. Cobalt chloride is commonly used as a moisture indicator because it changes color in the presence of water. It is also used as a source of cobalt in chemical reactions and as a supplement for livestock to prevent cobalt deficiency. In industry, cobalt chloride is used as a catalyst in various chemical processes, including the production of adhesives, plastics, and dyes. However, cobalt chloride is toxic and its use in products and applications is being increasingly restricted due to environmental and health concerns.

Perturbations in the pure rotational spectrum of CoCl (X3Φ): A submillimeter study

The millimeter/submillimeter-wave spectrum of the CoCl radical (X 3Φi) has been recorded using direct absorption techniques in the frequency range 340-510 GHz. This work is the first pure rotational study of this molecule. The radical was created by the reaction of Cl2 with cobalt vapor. Rotational transitions arising from the Ω=4, 3, and 2 spin-orbit components of Co35Cl have been measured, all of which exhibit hyperfine splittings due to the 59Co nucleus (I=7/2). Transitions arising from the Co37Cl species were also recorded, as well as those originating in the v = 1, 2, 3, and 4 vibrational states of both isotopomers. The spin-orbit pattern exhibited by the molecule is unusual, with the Ω=3 component significantly shifted relative to the other spin components. In addition, the regular octet hyperfine splittings become distorted above a certain J value for the Ω=3 transitions only. These effects suggest that the molecule is highly perturbed in its ground state, most likely a result of second-order spin-orbit mixing with a nearby isoconfigurational 1Φ3 state. The complete data set for Co35Cl and Co37Cl were fit successfully with a case (a) Hamiltonian but required a large negative spin-spin constant of λ=-7196 GHz and higher order centrifugal distortion corrections to the rotational, spin-orbit, spin-spin, and hyperfine terms. The value of the spin-spin constant suggests that the Ω=3 component is shifted to higher energy and lies near the Ω=2 sublevel. The hyperfine parameters are consistent with a δ3π3 electron configuration and indicate that CoCl is more covalent than CoF.
