The potential energies of the bonded terms, namely bonds (Figure (b)), angles (Figure (c)), and improper dihedral angles (Figure (d)) follow a similar trend. The higher potential energies at lower water contents could be explained by the bonded terms of the molecules being in a less energetically preferable configuration compared to other water contents, due to their tighter packing. These trends are opposite to those for the total potential energy, which are, however, not noticeably affected, as the fraction of potential energies of the bonded terms is relatively small.
