Chemical Physics Letters, 696, 139-143. doi:10.1016/j.cplett.2018.02.038 | Series/Report no.: | Chemical Physics Letters | Abstract: | The resultant energy of solvent H–O bond exothermic elongation by O:⇔:O repulsion, featured at <3100 cm −1 , and the solute H–O bond endothermic contraction by bond-order-deficiency, at 3610 cm −1 , heats up the (Li, Na, K)OH solutions. The solution temperature increases linearly with the number fraction of the ordinary O:H–O bonds transiting into their hydration states. The elongated H–O bond emits >150% the O:H cohesive energy of 0.095 eV that caps the energy dissipating by molecular motion, thermal fluctuation, diffusion, and even evaporation. Therefore, the intramolecular H–O bond relaxation dictates the OH − solvation bonding thermodynamics and the performance of basic solutions. | URI: | https://hdl.handle.net/10356/85920 http://hdl.handle.net/10220/48296 |
