氢键氢键hydrogenbond一个与电负性高的原子X共价结合的氢原子（X—H）带有部分正电荷，能再与另一个电负性高的原子（如Y）结合，形成一个聚集体X—H…Y的化学结合作用。X、Y原子的电负性越大、半径越小，则形成的氢键越强。例如，F—H…F是最强的氢键。氢键表面上有饱和性和方向性：一个H原子只能与两个其他原子结合，X—H…Y要尽可能成直线。但氢键H…Y之间的作用主要是离子性的，呈现的方向性和饱和性主要是由X和Y之间的库仑斥力决定的。氢键可以在分子内形成，称为内氢键；也可以在两个分子之间形成。分子间的氢键可使很多分子结合起来，形成链状、环状、层状或立体的网络结构。氢键的键能比较小，通常只有17～25千焦/摩尔。但氢键的形成对物质的性质有显著影响，例如使熔点和沸点升高；溶质与溶剂之间形成氢键，使溶解度增大；在核磁共振谱中氢键使有关质子的化学位移移向低场；在红外光谱中氢键X—H…Y的形成使X—H的特征振动频率变小并伴有带的加宽和强度的增加；氢键的形成决定蛋白质分子的构象，在生物体中起重要的作用。
