摘要:
Extending water ice and solvation research has led to new insight into the energetics and dynamics of explosions. It is uncovered that the intermolecular hydrogen bond (X:H-Y or HB with ‘:’ being electron lone pair of the electronegative constituent X, Y = O or N ) tension constrains and the super-HB (X::Y) or anti-HB (HH) compression fosters explosion. Both interactions raise the energy density by shortening all covalent bonds and stabilizes the energy carriers through their competition. The presence of the X:H-Y tension and HH for cyclo-N5- complexes, and X::Y for CNHO crystals, endows their constrained detonation while the absence of X:H-Y tension results in the unconstrained aquatic explosion of alkali metals and molten alkali halides. The lack of X::Y compression fosters no explosion of the molten NaCl and liquid NH3 combination.
