WebThe proton dynamics of PV and its sulfonated derivatives have been studied using high-resolution solid state 1 H MAS NMR. Variable temperature experiments were used to determine the activation energy for transportation of hydrogen bonded protons, found to be 22 ± 1 kJ · mol −1 for PV and 13 ± 1 kJ · mol −1 for PV–B25. The proton exchange … WebIts absorption spectrum is characterized by two intense bands in the visible region centered at 570 nm (ε = 15 000 M −1 cm −1) and 531 nm (ε = 13 000 M −1 cm −1) and the 1 H-NMR … mickey shorr port huron
