Abstract:
Broadband rotational spectroscopy is used to investigate the geometries of 3-methyl-3-oxetanemethanol and its complexes with up to six water molecules, which are produced in supersonic jets. The main low-energy isomers of these clusters are unambiguously identified in the spectra with the support of quantum-chemical calculations. The conformation of the 3-methyl-3-oxetanemethanol geometry is found to be influenced by the microsolvation effects. The hydrogen-bond arrangements in the hydrate complexes, which are governed by the water-water and water-solute interactions, exhibit characteristic configurations with increasing number of water molecules and resemble the main isomers of the corresponding pure water clusters. Evolution of the hydrogen-bonding structures from one-dimensional chains to two-dimensional rings and further to multicyclic three-dimensional networks is observed, which provides information about the build-up process.

Dehydration Synthesis
Dehydration synthesis (also called a condensation reaction) is the chemical process in which two molecules covalently link together to form a new molecule, along with the release of a water molecule. Many physiologically important compounds form by dehydration synthesis reactions, such as complex carbohydrates, proteins, DNA, and RNA.

Aldehydes and Ketones with Water: Hydrate Formation
The formation of hydrates is a reversible reaction. Hydrate formation is influenced by steric and electronic factors accompanying the alkyl substituents on the carbonyl group: The rate of hydrate formation increases with a decrease in the number of alkyl groups attached to the carbonyl carbon. Hence,...
