结论 很明显，随着新的数学计算方法的引入，以及应用群论方法来确定给定交换系统的线形中潜在存在的机械信息，动态系统中的核磁共振领域已经进入了一个令人兴奋的新阶段。过渡金属氢化物已被用作示例，因为这是我们迄今为止完成大部分研究的领域。这些方法显然可以应用于在核磁共振时间尺度上进行相互分子内交换的任何系统，只要它包含磁核。已经提到了 (CHs^ NPFé 的例子；我们已经分析了阳离子过渡金属 ML5 物种的光谱，目前正在研究其中可以获得机械信息。
Conclusion It is clear, with the introduction of the new mathematical approaches to computation, and with the application of group theoretical methods to the de-termination of the mechanistic information poten-tially present in the line shapes for a given exchanging system, that the field of nmr in dynamic systems has entered a new and exciting phase. Transition metal hydrides have been used as examples since this is the area in which the bulk of our research has so far been done. The methods can clearly be applied to any system undergoing mutual intramolecular ex-change on the nmr time scale, provided it contains magnetic nuclei. The example of (CHs^ NPFé has been mentioned; we have analyzed the spectra for, and are currently studying, cationic transition metal ML5 species where mechanistic information can be obtained.
