In order to gain insight into the strength of the intermolecular interactions stabilizing the clusters, we carried out CID experiments. Figure shows NCE-resolved breakdown curves for the (G) the pure ammonium bisulfate cluster as well as the mixed clusters with G and A are those resulting from the loss of neutral A and the loss of (A)(SA). The loss of A and (A)(SA) are chemically intuitive in the case of the (G) 0 (A) 3 (SA) 2 . This result is consistent with earlier work on thermal, surface-induced, and multiphoton-induced dissociation of ammonium bisulfate clusters. Both mixed clusters exhibit the exact same fragmentation pathways, indicating that it is energetically favorable to retain G in comparison to A or (A)(SA).
