Non-covalent interactions

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‐Covalent Interactions“, we emphasize how the new broadband microwave techniques have boosted the possibilities for analyzing larger clusters and weaker interactions with rotational resolution.

The forest of non-covalent interactions has more trees than expected. Read the minireview to check out why.

PCCP cover

A work on the intermolecular cluster pyridine-methane in collaboration with the group of  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 halomethanes.



A work in collaboration with the Pate group in Virginia examined the weakly-bound cluster of sevoflurane···benzene ans was published in Angewandte Chemie. The primary interaction is a relatively strong C-H···pi hydrogen bond. The presence of additional C-H···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.



J2IFAM meeting over

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···freon intermolecular complexes last Thursday 23rd.
