CHEMICAL-REACTION RATES AND SOLVATION DYNAMICS IN ELECTROLYTE-SOLUTIONS - ION ATMOSPHERE FRICTION

We consider the influence of ion atmosphere dynamics on a model dipolar isomerization in an electrolyte solution, as well as on the time dependent fluorescence (TDF) of a dipolar solute. The impact of the resulting ion atmosphere friction on reducing the reaction rate below the equilibrium solvation transition state theory value can sometimes be pronounced. Connections of this friction to the TDF dynamics are indicated for solvents both of low and high polarity.
