Abstract
Mg(CF3SO3)2-diglyme electrolytes containing adequate formamide amounts were studied for the first time by Raman spectroscopy in the range 0.1–1.1 mol kg−1. The ion association was experimentally identified at the υs(SO3), δas(CF3 + SO3) and δs(CF3) regions of the anion, and the high sensitivity of the symmetric angular deformation mode revealed that such a phenomenon is present from the most diluted salt solution. Quantum chemical computations were also employed for the first time to assign the most intense bands of non-associated triflate and associated to the Mg(II) cation. Despite the high ion association degree, the presence of formamide molecules in the solvation structures is an important parameter and may have substantial impact on the electrochemical performance of this new formulation.
期刊介绍:
Chemical Physics Letters has an open access mirror journal, Chemical Physics Letters: X, sharing the same aims and scope, editorial team, submission system and rigorous peer review.
Chemical Physics Letters publishes brief reports on molecules, interfaces, condensed phases, nanomaterials and nanostructures, polymers, biomolecular systems, and energy conversion and storage.
Criteria for publication are quality, urgency and impact. Further, experimental results reported in the journal have direct relevance for theory, and theoretical developments or non-routine computations relate directly to experiment. Manuscripts must satisfy these criteria and should not be minor extensions of previous work.
