Weband 13C/12C isotope exchange, as well as electrochemical Stark effects. The latter presents the shift of the vibrational frequency of the adsorbate with electrode potential. To the first order of the theory, the frequency shift Δν by electric field ~F can be written as Δν≈− j~μ · ~ Fj·cosφ,whereΔ! is the change in the local WebApr 9, 2024 · In summary, we have systematically investigated the effect of the position and degree of fluorination in EA solvent on electrochemical performances. We reveal that a high degree of fluorination or fluorination close to ester group imposes more electron-withdrawing effect, resulting in low atomic charges, low binding energies to Li + ions, low ...
