Spectra of triply ionized CO(2) have been obtained from photoionization of the molecule using soft x-ray synchrotron light and an efficient multi-electron coincidence technique. Although all states of the CO(2) (+++) trication are unstable, the ionization energy for formation of molecular ions at a geometry similar to that of the neutral molecule is determined as 74 ± 0.5 eV.
三重态离子化的 CO(2) 的光谱是通过使用软 X 射线同步加速器光和高效的多电子符合技术对分子进行光离子化获得的。尽管 CO(2)(+++)三价阳离子的所有状态都是不稳定的，但在类似于中性分子的几何形状下形成分子离子的电离能被确定为 74±0.5eV。
