Figure 11. Fractional change in the Br*/Br branching ratio relative to the case when no DSC field is applied. The branching fraction is measured by taking the ratio of the integrated intensities of the two peaks in Figure 11 as a function of ∆t, the control pulse time delay. At early and late delays, the field-free branching ratio is observed, demonstrating the reversible nature of the DSC interaction.
