Heterogeneous ozone chemistry occurring on aerosols is driven by interfacial chem- istry and thus affected by the surface state of aerosol particles. Therefore, the effect of electrolytes on the structure of interfacial water has been under intensive investi- gation. However, consequences for energy dissipation rates and mechanisms at the interface are largely unknown. Here, we use time-resolved sum frequency generation spectroscopy to reveal that the relaxation pathway is the same for neat water-air as for aqueous solutions of NaSO and NaCO , although the interfacial aqueous structure is substantially modified. We further show that similar lifetimes are extracted from all investigated systems and that these lifetimes show an excitation frequency dependent relaxation time from 0.2 ps up to 1 ps. Hence, despite static SFG on the same systems revealing that the interfacial aqueous structure changes upon adding electrolytes, the dynamics are indistinguishable for both pure water and different electrolyte solutions.

Substances that dissociate into two or more ions, to some extent, in water. Solutions of electrolytes thus conduct an electric current and can be decomposed by it (ELECTROLYSIS). (Grant & Hackh's Chemical Dictionary, 5th ed)
A thiazide diuretic often considered the prototypical member of this class. It reduces the reabsorption of electrolytes from the renal tubules. This results in increased excretion of water and electrolytes, including sodium, potassium, chloride, and magnesium. It is used in the treatment of several disorders including edema, hypertension, diabetes insipidus, and hypoparathyroidism.
The balance of fluid in the BODY FLUID COMPARTMENTS; total BODY WATER; BLOOD VOLUME; EXTRACELLULAR SPACE; INTRACELLULAR SPACE, etc., maintained by processes in the body that regulate the intake and excretion of WATER and ELECTROLYTES, particularly SODIUM and POTASSIUM.
The pattern of any process, or the interrelationship of phenomena, which affects growth or change within a population.
