分子间相互作用在化学和化学反应中起着重要作用[1-8]，从生物分子中碱基对的氢键到溶液中金属阳离子与冠醚的结合。此外，刘易斯酸通常在有机和无机化学反应中用作催化剂[9-11]，并且催化模式通常被认为涉及中间体络合物的形成[12-13]。用分子方法来描述这些相互作用需要尽可能完整地了解分子复合物或加合物的结构和键合。大多数情况下，这些是1：1二元复合物，通常被称为异二聚体，尽管可以形成更大的加合物和聚集体。随着理解分子间相互作用的重要性，许多不同的实验方法已经被采用，从许多经典的溶液相研究开始，包括光谱和热力学测量。最近，气相中的研究提供了重要的补充信息，特别是在超音速光束中获得的信息
Intermolecular interactions play a major role in chemistry and chemical reactions [1-8], from the hydrogen bonding of base pairs in biomolecules, to the binding of metal cations to crown ethers in solution. In addition, Lewis acids are often employed as catalysts in both organic and inorganic chemical reactions [9-11], and the mode of catalysis is often thought to involve formation of an intermediate complex [12-13]. A molecular approach to the description of these interactions requires as complete a knowledge as is possible about the structure and bonding in molecular complexes or adducts. Most often these are 1: 1 binary complexes, often referred to as heterodimers, although certainly larger adducts and aggregates may be formed. With the great importance of understanding intermolecular interactions, many different experimental approaches have been employed, starting with the many classical solution phase studies involving spectroscopic and thermodynamic measurements. More recently, studies in the gas phase have provided important, complementary information to that obtained in solutions, particularly the supersonic beam
