Bond bundles possess several qualitative and quantitative properties, many of which can be calculated and analyzed. Early in bond bundle research, it was found that bond bundle valance electron population recovers bond order , total electron populations were found to correlate with the interfacial energy of a metal-ceramic interface , and the shapes of bond bundle surfaces were shown to be indicative of chemical functionality and delineate molecular regions prone to nucleophilic or electrophilic attack . 6 The topology of the gradient bundle condensed charge density recovers the same bond bundle surfaces as the previously 6 Previously, bond bundles were analyzed using a method of explicit bond bundle surface identification, rather than implicit identification using the gradient bundle condensed charge density as at present. used method , but with higher accuracy and generalizable to a broader range of chemical and condensed phase systems.
