The Role of Non?Covalent Interactions on Cluster Formation: Pentamer, Hexamers and Heptamer of Difluoromethane

The role of non-covalent interactions (NCIs) has broadened with the inclusion new types and a plethora weak donor/acceptor partners. This work illustrates potential chirped-pulse Fourier transform microwave technique, which revolutionized field rotational spectroscopy. In particular, it been exploited to reveal NCIs’ in molecular self-aggregation difluoromethane where pentamer, two hexamers heptamer were detected. development automated assignment program sophisticated computational screening protocol was essential for identifying homoclusters conditions spectral congestion. major dispersion forces leads less directional more distorted structures than those found polar clusters, although detailed analysis demonstrates that dominant interaction energy is pairwise interaction. tetramer cluster identified as structural unit larger representing maximum expression bond between dimers.
