Applying Computational Spectroscopy Methods to Raman Spectra of Dicationic, Imidazolium-Based, Ionic Liquids.

Studying ionic liquids (ILs) through computational methods is one of the ways to accelerate progress in the design of novel and potentially green materials optimized for task-specific applications. Therefore, it is essential to develop simple and cost-effective computational procedures that are able to replicate and predict experimental data. Among these, spectroscopic measurements are of particular relevance since they are often implicated in structure-property relationships, especially in the infrared spectral region, where characteristic absorption and scattering processes due to molecular vibrations are ultimately influenced by the surrounding environment in the condensed phase. In this frame, we validate,
