Hydration interactions beyond the first solvation shell in aqueous phenolate solution

We investigate the orientational dynamics of water molecules solvating phenolate ions using ultrafast vibrational spectroscopy and density functional theory-based molecular dynamics simulations.

Antenna-enhancements of molecular vibrational responses in ultrafast infrared spectroscopy

We demonstrate surface-enhanced ultrafast vibrational spectroscopy employing periodic arrays of infrared-resonant gold nanoantennas. The antenna-enhancements of molecular vibrational responses are analytically formulated with a simple coupled-dipole model, and the linear/nonlinear local signal enhancements are evaluated to be ~104 and 107, respectively.

Li-Ion solvation in propylene carbonate electrolytes determined by molecular rotational measurements

We report the solvation structure of Li+ in LiPF6–PC solutions using ultrafast vibrational spectroscopy. The results illustrate the salt concentration-dependent solvation structures, in accordance with the variation of ion conductivity.

Femtosecond infrared spectroscopy reveals the primary events of the ferrioxalate actinometer

Ultrafast vibrational spectroscopy unravels the primary processes of Hatchard and Parker's ferrioxalate actinometer – a widely used tool in the photochemistry community.

Using molecular vibrations to probe exciton delocalization in films of perylene diimides with ultrafast mid-IR spectroscopy

Ultrafast vibrational spectroscopy provides a direct comparison exciton delocalization in crystalline perylenediimides that informs their use in organic electronic applications.
