The noncovalent interaction A, portrayed in Figure , can occur with, and increase the strengths of, other types of interactions, especially the DDDA and DDSA types. The majority of A+DDDA and A+DDSA interactions are obtained in larger clusters; in most cases, the water clusters larger than the trimer are able to accommodate secondary interactions between aliphatic hydrogens and the water cluster. However, in some cases, an A+SDSA type complex can be observed, as shown in Figure . Plotting the benchmark BE using this classification of noncovalent interactions results in Figure . From this graph, and taking the most stable complex in each case, type A emerges as the weakest of the probewater complex interactions because it involves primarily dipole-dipole interactions and C-H
