Time-resolved photoelectron spectra for following charge transfer from the iodide to the water cluster in . Time steps are indicated on the time axis.
(Color) (a) Dynamics of the measured electron kinetic energy (eKE) with pump-probe delay for a range of clusters. Data points are indicated as such in the legend and single exponential decay fits are shown as solid lines. (b) Time constants taken from single exponential fits [see (a)] to the shift in eKE for both (full circles) and (open circles).
(Color) Comparison between the photoelectron spectra, plotted in terms of electron binding energy , taken for at times (a) and (b) and that taken for under conditions where the additional isomers could be observed (blue line) (Ref. 12). The vertical dashed line indicates the vertical binding energies (VBE) of isomer II and isomer I in (a) and (b), respectively. (c) Shows a comparison between the VBEs measured around zero pump-probe delay and at long delay, and the VBEs reported for various isomers of (Ref. 12). The symbols are shown in the legend, where the data for small clusters are taken from Ref. 8.
Representative energy diagram showing schematically the dynamics observed. Upon CTTS excitation, the cluster resembles isomer II of the bare cluster. The cluster then undergoes spontaneous isomerization to form a cluster characteristic of isomer I.
