Temperature-Structure Relationship the energy differences between structures A and B at warmer temperatures also heighten the likelihood of both structures coexisting. In the case of the (G) 2 (A) 0 (SA) 1 and the (G) 2 (A) 1 (SA) 2 clusters, structure A remains the calculated minimum energy structure while a significant number of the other structures computed for these two clusters fall within 1 kcal mol -1 at higher temperatures. As for (G) 3 (A) 0 (SA) 2 , structure E is the minimum at 217 K and 298 K and structure A is only slightly higher in energy. Put together, it is evident that temperature plays a significant role in determining the minimum energy structure as well as the energetic ordering of close-lying isomers of the five clusters studied in this work.
