An investigation on the thiophenol dimer and trimer was published in the Journal of Physical Chemistry Letters. The weakly-bound dimer adopts a stacked structure, while simultaneously maintaining a weak S-H路路路S hydrogen bond. Two isomers were detected for the dimer in the gas-phase. Notoriously, a large-amplitude motion was observed in one of the dimers, exchanging the proton donor and aceptor thiol groups.
We published in Chemistry: A European Journal a Minireview on rotational studies of non-covalent interactions, which appeared in the Reviews Showcase section of the Journal. In the article, entitled “The Hydrogen Bond and Beyond: Perspectives for Rotational Investigations of Non鈥怌ovalent Interactions“, we emphasize how the new broadband microwave techniques have boosted the possibilities for analyzing larger clusters and weaker interactions with rotational resolution.
A work on the intermolecular cluster pyridine-methane聽in collaboration with the group of聽 Walther Caminati has been chosen as cover of PCCP. Methane behaves in the complex as a noble gas, binding on top of the aromatic ring. This T-shape structure contrasts with the in-plane structure of other pyridine clusters involving聽halomethanes.
A work in collaboration with the Pate group in Virginia examined the weakly-bound cluster of sevoflurane路路路benzene ans was published in Angewandte Chemie. The primary interaction is a relatively strong C-H路路路pi hydrogen bond. The presence of additional C-H路路路F weak interactions hinders the six-fold symmetric internal rotation of benzene around sevoflurane. This is probably the first time that such a V6 barrier has been determined in a intermolecular complex.
The VI meeting of young researchers in Atomic and Molecular Physics (J2IFAM-2014) organized in Bilbao (January 22-24) is now over. Montse gave a talk on pyridine路路路freon intermolecular complexes last Thursday 23rd.
