chlorine, leading to the [Cu n Cl n+1 ] − products (b), where the insets showed the structural sketch in

concluded, which coincides with the reaction kinetics through the proposed reaction
channels, as shown in Fig. 4.8.
In addition to the mass spectrometric observation, it is noteworthy that alkali halide
clusters have also been extensively studied and provided a better understanding on
the physical basis of ionic crystal growth [59–62]. As the group IB coinage metals
(i.e., Cu, Ag, Au) have electronic configurations characterized by a closed d-shell
and a single s-valance electron, it is believed that the coinage metal clusters may
react in a similar fashion to alkali metals [63–68]. Extensive investigations both
