Double‐charge‐transfer spectroscopy has been used to confirm that CF + and CCI + can exist for times greater than several μs in electronically excited states. From the spectra obtained it was shown that those states are 4.7 ± 0.7eV and 3.3 ± 0.5eV above the ground states for CF + and CCI + , respectively. The experimental technique is quite sensitive to the detection of long‐lived excited states and it is shown for CCI + that the relative populations of the excited and ground states are markedly different when CFCI 3 and CF 2 ClCFCI 2 are used as the precursor molecules in the dissociative‐ionization process.
