Notizen:
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 CFCI3 and CF2ClCFCI2 are used as the precursor molecules in the dissociative-ionization process.
