本文介绍了液氨在两种温度状态下的液-汽共存曲线的中子衍射测量。本文研究了三种各向同性的氢化和氘代氨混合物，并在213 K和273 K下提取了三种径向原子-原子分布函数。取向不相关的分子的部分径向分布函数的实验结果的比较，显示了一些证据，在液氨中的氢键，但这是比在环境条件下发现在水中不太明显。
Neutron diffraction measurements on liquid ammonia at two temperature states on the liquid‐vapor coexistence curve are presented. Three isotropic mixtures of hydrogenated and deuterated ammonia have been studied and the three radial atom–atom distribution functions extracted at 213 K and 273 K. The comparison of the experimental results with the partial radial distribution functions for orientationally uncorrelated molecules, shows some evidence for hydrogen bonding in liquid ammonia but this is much less pronounced than that found in water under ambient conditions.
