It is now well admitted that hydrophobic interactions and hydrogen bonds are the main forces driving protein folding and stability. However, because of the complex structure of a protein, it is still difficult to separate the different energetic contributions and have a reliable estimate of the hydr...
The structural-thermodynamic model for the quantitative description of unconventional hydrogen bonding with the hydrogen atom in hydrides (H2 bond) is presented. The energy of H2 bonds is considered by using the interaction between water molecules and BH4/-, B10H10/2-, B12H12/2-, and other ani...

Gas hydrates are clathrate physical compounds, in which the molecules of gas are occluded in crystalline cells, consisting of water molecules retained by the energy of hydrogen bonds. All gases can form hydrates under different pressures and temperatures. The crystalline structure of solid gas hydrate...
A hydrogen bond energy of −4.72 kcal/mole was found for the dimer in the most favorable configuration. We find that triplets with sequential hydrogen bonds significantly stabilize condensed phases which incorporate them, and they exert a strong compressive effect to reduce nearest-neighbor distances...

Hydrogen bond energy is around ... kJ mol−1 View Solution A : Bond energy is equal to enthalpy of formation with negative sign. R: Bond energy is energy required to dissociate 1 mole single bond. View Solution The bond dissociation energy depends upon the nature of the bond and nature...
the cost of hydrogen storage systems is too high; durability of hydrogen storage systems is inadequate; hydrogen refuelling times are too long; high-pressure containment for compressed gas and other high-pressure approaches limits the choice of construction materials and fabrication techniques, within we...
A similar trend is also observed in case of the primary C–H bonds, that is, the α-C–H bond strengths increase with successive substitution of the β-hydrogens by fluorine atoms, although the effect is not as linear as it is for the trifluoromethyl series, which is probably du...
In ionic clusters, we observe a decrease of hydrogen bond strength with an increasing number of aromatic rings in the chromophor, whereas the neutral binding energy increases in this case. 展开 关键词: Experimental/ binding energy hydrogen bonds molecular clusters organic compounds Rydberg states ...
