致谢。作者衷心感谢美国国家科学基金会 (W. leN.) 和美国公共卫生服务中心 (EHW; Grant GM-21430) 对这项工作的支持。确保反应完全，并在常压下在同一玻璃器皿中进行平行实验。根据刚才引用的证据，可以合理地假设松散离子对的寿命在压力下应该增加，并且紧密离子对形成和后者塌陷为共价产物的速率应该被延迟。因此，从表面上看，对映体松散对的平衡应相应地通过施加压力来促进。
Acknowledgments. The authors gratefully acknowledge support of this work by the National Science Foundation (W. leN.) and by the US PublicHealth Service (EHW; Grant GM-21430). ensure complete reaction, and parallel experiments were carried out in the same glassware at atmospheric pressure. On thebasis of the evidence just quoted it is reasonable to assume that the lifetime of the loose pair should increase under pressure and that therates of tight ion-pair formation and of collapse of the latter to covalent product should be retarded. Thus at face value the equilibration of the enan-tiomeric loose pairs should correspondingly be promoted by the application of pressure.
