File Name : figure_s1.png Caption : figure s1. data for the same four (of ten total) ions shown in figure 1a but processed with a longer stft segment length (100 ms instead of 25 ms). this leads to lower time resolution for the ion emission event but higher frequency resolution so that the frequencies of ion iv before and after ion emission are clearly resolved. File Name : figure_s2.png Caption : figure s2. the frequency of ion emission events for clusters of (a) cacl2 and (b) lacl3 showing a higher number of multiple emission events for single lacl3 clusters compared to cacl2 clusters.
