摘要

The electronic absorption spectrum of NCCN+ in the gas phase was measured at -15 K in a 22-pole ion trap. The spectra show two band systems assigned to the C2Πu-X2Πg and D2Πu-X2Πg transitions with origin band maxima at 17 363 (3) and 33 409 (5) cm-1, respectively. Both absorptions show distinct vibrational structure with progressions in ν2 as well as combinations of double quanta excitations in ν4 and ν5. Rotational structure of the 00 0 bands could not be resolved, which indicates that the C2Πu and D2Πu states have a lifetime on the order of a hundred femtoseconds because of fast intramolecular processes.
