Abstract

One technique based on the difference spectra was developed to study the state of water in supersaturated Mg(NO₃)₂ aerosols. The technique could be derived from the observation that the Raman scattering and infrared absorbance cross sections of molecular vibrations of interest remain practically constant from diluted solutions to supersaturated aerosols. The spectra of solvated water were obtained and primarily related to the first hydration layers of solute molecules in supersaturated Mg(NO₃) ₂ aerosols. Based on this investigation, a chain structure was proposed to occur in the supersaturated Mg(NO₃)₂ aerosols at low relative humidities (RHs).
