Quantum chemical investigations on molecular clusters

SR Gadre, SD Yeole, N Sahu - Chemical reviews, 2014 - ACS Publications
A cluster is an aggregate of bound atoms or molecules, intermediate in size between a
molecule and a bulk solid. Clusters of a variety of molecules are receiving increasing …

Hydrogen bond networks of ammonia clusters: What we know and what we don't know

A Malloum, J Conradie - Journal of Molecular Liquids, 2021 - Elsevier
Understanding the behaviour of liquid ammonia is subjected to understanding the hydrogen

Exploration of the potential energy surfaces of small ethanol clusters

A Malloum, JJ Fifen, J Conradie - Physical Chemistry Chemical …, 2020 - pubs.rsc.org
The potential energy surfaces (PESs) of the ethanol clusters become increasingly complex
as the cluster size increases. This is mainly due to the fact that there are up to three stable …
