微波波谱是一种微波频段的波谱学方法,近年来在研究分子系统结构及分子间弱相互作用上发展迅速,是一种高分辨率和高灵敏度的分析工具.本文介绍了它的原理及应用,尤其是对脉冲喷射傅里叶变换微波谱仪研究范德华力配合物、氢键配合物、弱氢键配合物、卤键配合物等弱相互作用体系的微波转动谱也作了简要的综述.
Microwave spectroscopy, which works at microwave frequencies, developed rapidly in recent years as an analytical tool for studying molecular geometrical structures and intermolecular interactions with high resolution and sensitivity. This review introduces the principles underlying this technique, as well as its applications in studying the weakly bounded complexes, namely van der Waals complexes, hydrogen bond complexes and halogen bond complexes. The pulsed-nozzel Fourier transform microwave spectrometer was also briefly introduced.
