The clusters were initially generated via ESI using a Thermo Scientific LTQ XL linear ion trap mass spectrometer. The relative stability of the clusters was characterized via collision induced dissociation (CID) experiments. Each cluster of interest was subjected to collisions with background gas (Helium), ultimately leading to fragmentation. The m/z-dependent normalized collision energy (NCE) parameter of the LTQ XL was utilized (in increments of 2.5% starting from 0-10% NCE and increments of 5% between 10-20% NCE) to achieve the step-wise dissociation of the clusters. The activation time for each CID experiment was 30 ms. Each plotted mass spectrum is an average of 100 scans. NCE-resolved breakdown curves were generated using a home-built Python code that quantifies the absolute intensities of fragments as a function of NCE.
