Nanoemulsions have attracted considerable attention in recent years due to their unique potential applications in drug delivery, oil recovery, and as nanoreactors for producing polymers and nanomaterials. They are also predicted to be increasingly important commercially since significantly less emulsion stabilizing surfactant is required for their function.  The focus of this presentation will be on our measurements of the molecular structure and assembly of several surfactants and the oil and water solvents examined at the surface of regular and reverse nanoemulsions.  How this assembly and structure varies as these surfactants adsorb to the planar oil/water interface will also be presented and compared.  The studies involve measuring the vibrational spectroscopy at the nanoemulsion and planar interface using vibrational sum frequency spectroscopy in a scattering and total internal reflection geometry respectively.  Surface tension, light scattering, zeta potential and computational methods are used to complement the spectroscopic studies. <br/>
