在化学领域中，valence bond theory指的是“价键理论”。价键理论是一种关于化学键的基本理论。是海特勒和伦敦于1927年用量子力学处理氢分子所得结果的推广和发展。基本要点是：（1）若原子A和原子B各有一未成对电子且自旋相反，则可互相配对而构成共价单键，如原子A和原子B各有两个或三个未成对电...
二 价键理论 ( Valence Bond Theory ) 1927年,Heitler 和 London 用量子力学处理氢气分子 H2 ,解决了两个氢原子之间的化学键的本质问题,使共价键理论从经典的 Lewis 理论发展到今天的现代共价键理论。;从图中可以看出,r = r 0 时, V 值最小,为 V = -D ( D 0 ,- D 0 ) ,; H2 中的化学键,...

Volume 10. Valence Bond TheoryDavid Cooper
According to the valence bond theory, Electrons in a molecule occupy atomic orbitals rather than molecular orbitals. The overlapping of atomic orbitals results in the formation of a chemical bond and the electrons are localized in the bond region due to overlapping. ...
