价键理论 Valence bond theory
（重定向自Valence Bond）
价键理论（Valence bond theory，VB理论）是一种获得薛定谔方程近似解的处理方法，又称为电子配对法。价健理论与分子轨道理论是研究分子体系的两种量子力学方法。它是历史上最早发展起来的处理多个化学键分子的量子力学理论。价键理论主要描述分子中的共价键及共价结合，核心思想是电子配对形成定域化学键。

In chemistry, valence bond (VB) theory is one of two basic theories, along with molecular orbital (MO) theory, that were developed to use the methods of quantum mechanics to explain chemical bonding. It focuses on how the atomic orbitals of the dissociated atoms combine to give individual chemical bonds when a molecule is formed. In contrast, molecular orbital theory has orbitals that cover the whole molecule.
