dipole-dipole就是偶极与偶极之间的作用,主要就是极性分子中正负电荷中心不重合而产生了极性,这样偶极之间就有了作用力. London dispersion force:非极性分子间仍存在吸引力.这起因于分子内电子和原子核的不断运动,产生分子的瞬间偶极矩,并在邻近分子中诱导一个偶极矩.它们之间的相互作用产生净吸引力.1930年London应用...
hydrogen bond 就是氢键了,就是H由于显正电,形成质子而容易被其他外层电子比较多的原子吸引而产生的键,像O 阿,S 阿,N 之类的.dipole-dipole就是偶极与偶极之间的作用,主要就是极性分子中正负电荷中心不重合而产生了极性,这样偶极之间就有了作用力.London dispersion force：非极性分子间仍存在吸引力。...
Here, a dimensionally stable and self-healing PEM is developed by tuning the hydrogen bond and dipole-dipole interactions between the mature perfluorinated sulfonic acid (PFSA) and a self-healing copolymer, which is specifically synthesized with hexafluorobutyl acrylate (HFBA) and acrylic acid (AA)...

A hydrogen bond is a type of attractive (dipole-dipole) interaction between an electronegativeatomand ahydrogenatombondedto another electronegative atom. This bond always involves a hydrogen atom.Hydrogen bondscan occur betweenmoleculesor within parts of a single molecule. ...
Hydrogen bondsare stronger and an important form of dipole–dipole interactions.Hydrogen bondingoriginates when at least one dipole contains electropositive hydrogen. The bond exhibits anelectrostatic attractionof ahydrogen atomfor a strongly electronegative atom such as oxygen, nitrogen, or fluoride. Beca...
The hydrogen bond is a dipole-dipole bonding interaction between a hydrogen atom, which is covalently bonded to an electronegative atom (donor), and another electronegative atom (acceptor) [117]. The donor and acceptor atoms are normally oxygen, nitrogen or fluorine. The bond energy for a hydrog...

Basically, the protons are bound to the lattice structure by a square-well potential field, perfectly symmetrical with respect to the middle point for each hydrogen bond, while only two protons appear close to a given phosphate group the other two being farther away, according to the principle ...
Intermolecular forces that mediate interactions between molecules include hydrogen bonding, hydrophobic interaction, dipole-dipole interaction, and van der Waals forces. Hydrogen bonding is an electrostatic attr
