Following ion pairing/dissociation at the microscopic level by spectroscopic techniques

Résumé

Ion pairs resulting from the association of a cation and an anion of opposite charge are ubiquitous supramolecular objects in solution and biological media, but remain difficult to characterize due to the diversity of the possible structures and their frequent transient nature. To study the structures and properties of these objects in various envrionments from gas to solution, the IONPAIRS project aimed at developping new spectroscopic approaches combining different experimental and theoretical techniques. This presentation will focus on the findings about microsolvated and solvated ion pairs, including: the elucidation of ion dissociation schemes by microhydration [1], the characterization of water mediated ionic interactions [2] and the identification of supramolecular structures in solution [3].
