Solvent Polarity under VSC

We are pleased to announce the acceptance in JACS of a new paper presenting results obtained in collaboration with Joseph Moran’s group. By coupling some vibrational bands of alcoholic solvents with cavity modes, we showed that their polarity is influenced, by measuring the solvatochromic response of Reichardt’s dye. The shift in the absorption spectrum of the dye depends on the length of the solvents alkyl chain, indicating that dispersion forces are impacted by strong coupling and may be critical to understand how vibrational strong coupling influences chemical reactivity. Congratulations to all !
