| The composition, structure, and reactivity of tropospheric aerosol particles play an important role in climate regulation. Some of the most important reactions on, and in, these particles and in other aqueous media in our environment involve compounds containing sulfur. We report our recent investigations of the intermolecular structure and bonding of a variety of naturally occurring tropospheric sulfur compounds at the vapor/water interface using vibrational sum-frequency spectroscopy. The results of these studies provide insights into their adsorption, reactivity, and interactions with water molecules. The orientation of these adsorbates and their distinct influences on the water structure will be discussed. |
