Carbonate (CO3) is an unstable product of reactions between carbon dioxide (CO2) and atomic oxygen (O).[1] It is different from the carbonate ion (CO32-). It has also been detected in reactions between carbon monoxide, CO, and molecular oxygen, O2. Among other places it has been shown to be created in the drift zone of a negative corona discharge.[2] This pathway arises from reactions between carbon dioxide and atomic oxygen ions, created from molecular oxygen by free electrons in the plasma. Carbon trioxide is a liquid.
Three possible isomers of carbon trioxide exist, denoted Cs, D3h, and C2v. The C2v state has been shown by various studies to be the ground state of the molecule.[3]
