摘要：

A novel Doppler free coincidence time-of-flight technique is presented. The technique allows kinetic energy release spectra to be obtained at vibrational resolution. The only limitation of the technique from a resolution point of view is the thermal rotational distribution in the neutral ground state, 25 meV FWHM at 300 K, which is directly reflected in the line profiles. As a test case the CO2+ ion is studies. Well resolved vibrational progressions are observed for the first time in a coincidence kinetic energy release spectrum.
