The tetrahedrally-coordinated structure and the unique coupling HB foster water a homogeneous and ordered fluctuating crystal . The identical members of electron lone pairs ":" and protons (H + ) reserve the configuration, number, and orientation of the HBs over wide ranges of temperature and pressure. Being the unique and efficient functional unit, HB relaxation in segmental length and energy determines uniquely performance of water under a load of perturbation. Ez of a bond between z-coordinated atoms . Where m is the bond nature index that correlates the bond energy to the bond length in the form of Ez ∝ dz -m . The BOLS-NEP notion indicates that a bond between fewer-coordinated atoms becomes shorter and stiffer. Bond contraction densifies electrons populated in the core and bonding orbitals, while bond stiffening deepens the potential that entraps electrons. These densely entrapped electrons, and meanwhile, polarize the edge atoms, turning them into dipoles that create topological states.
