FIG. 1.

Model potential energy surfaces describing a dynamic resonance in a dissociating molecule. Population is transferred from the ground state 1 to an excited dissociative state 2. At some point later in time, a second laser pulse promotes the population to state 3.

FIG. 2.

Fragment ion yields as a function pump-probe delay in (top) and (bottom). Each plot shows the primary fragments during the charge-transfer dynamic resonance. All curves for a given molecule are scaled by the same factor. The pump pulse intensity was , while the probe pulse was approximately one order of magnitude lower.

FIG. 3.

Fragment ion yields as a function pump-probe delay in , showing the primary fragments. The curves are scaled as indicated in the legend. The pump pulse intensity was , while the probe pulse was approximately one order of magnitude lower.

FIG. 4.

Fragment ion yields as a function pump-probe delay in (a) and (b). Enhanced ionization is seen in the (a) and (b) fragments (black, solid line). The red, dotted lines plot the fragment for comparison. Note the different time axes for the two molecules. All curves are individually normalized. The pump pulse intensity was , while the probe pulse was 0.5–1 times lower. Wave packet simulations on calculated PESs for both molecules are included as insets.

FIG. 5.

Ion yield as a function of probe pulse peak intensity for the dynamic resonances of charge transfer (in ) and enhanced ionization (in TFA). Panel (a) plots for both CT and EI, while panel (b) plots the partner fragment ( for CT and for EI). Both curves for each molecule are scaled by the same factor.

FIG. 6.

Fractional ion yield as a function of pump pulse peak intensity in . The three relevant fragment yields are plotted as a percentage of the total ion yield of all prominent fragments. Below the total yield drops quickly to zero, and noise begins to dominate.
