Sevoflurane dimer cover in PCCP

A collaborative study between Pate’s group (Virginia University), Lesarri’s group (University of Valladolid) and our group concluded in PCCP publication which was highlight as Journal cover by the journal. Phys. Chem. Chem. Phys., 2015,17, 18282-18287.

In this work we have examined the stereoselectivity of molecular recognition between two molecules of the anesthetic sevoflurane using broadband rotational spectroscopy. The transient axial chirality of sevoflurane is revealed upon the formation of the dimer, as two different diastereoisomers made of either homo- or heterochiral species are detected in a supersonic jet expansion. In both clusters the complex is stabilized by a primary C–H···O hydrogen bond, assisted by weak C–H···F interactions. This intermolecular binding regime is characterized by a mixture of electrostatic and dispersive interactions, midway between classical hydrogen bonds and van der Waals clusters.
