Does Ammonia Hydrogen Bond? | Science - AAAS
Spectroscopic characterizations of the stereochemistry of complexes of ammonia (NH 3) have strongly confirmed some long-held ideas about the weak interactions of NH 3 while casting doubt on others. As expected, NH 3 is observed to be a nearly universal proton acceptor, accepting hydrogen bonds from even some of the weakest proton donors.

Understanding the Hydrogen-Bonded Clusters of Ammonia …
An ammonia molecule can donate and accept up to three hydrogen bonds. Ammonia clusters are constituted of ammonia molecules linked by hydrogen bonds. The hydrogen bond network of ammonia clusters is related to ammonia’s properties.

2020年12月4日 · Hydrogen bonding in ammonia and water dimers causes an enhancement of the intensity of the hydrogen stretching bands by a factor of four and three, resp. Two types of the hydrogen bonded clusters show different size dependence of the IR intensity per hydrogen bond.
Understand the concept of hydrogen bonding in ammonia
Hydrogen bonding can be described as the process of forming hydrogen bonds that are an attractive intermolecular force’s special class, which arises because of the dipole-dipole interaction between the hydrogen atom and highly electronegative atom.

2022年7月28日 · Here, we use quantum molecular dynamics simulations to investigate hydrogen bond structure and lifetimes in two ammonia phases: liquid ammonia and crystalline ammonia-I.
both H20 and HF readily form hydrogen bonds, both as donors and as acceptors of the hydrogen bond. Although NH3 vigorously accepts hydrogen bonds in the gas phase, there is yet no example in which NH3 acts as a hydrogen-bond donor. The stereochemistry of the weak interactions of ammonia is dominated by its lone-pair
Does Ammonia Hydrogen Bond? - Semantic Scholar
Does Ammonia Hydrogen Bond? A critical evaluation of the work that has been done to gather evidence, as well as of earlier work involving condensed-phase observations, suggests that NH3 might well be best described as a powerful hydrogen-bond acceptor with little propensity to donate hydrogen bonds.

2022年7月28日 · Here, we use quantum molecular dynamics simulations to investigate hydrogen bond structure and lifetimes in two ammonia phases: liquid ammonia and crystalline ammonia-I. Unlike liquid water, which has two covalently bonded hydrogen and two hydrogen bonds per oxygen atom, each nitrogen atom in liquid ammonia is found to have only one hydrogen ...
