Effects of Salt Concentration on the Structure and Vibrational Sum Frequency Generation Spectra of Liquid/Vapor Interfaces of Aqueous Solutions of Metal Nitrates

The effects of varying salt concentration on the structure of the liquid/vapor interfaces of aqueous solutions of NaNO3, Mg(NO3)2, and Ca(NO3)2 salts are investigated using molecular dynamics simulations and vibrational sum frequency generation (VSFG) spectral calculations.
