Summary
Since the Romans first spread oil on water to calm the raging seas, curiosity has persisted about the unique nature of the interface between water and a hydrophobic liquid. This presentation will focus on our most recent efforts in understanding the molecular structure of this interface and the unique environment it provides for ions, molecules, macromolecules, and nanoparticles that are drawn into its inner realm. Insights gained from these studies come from a combination of vibrational sum frequency spectroscopy, pendant drop surface tension measurements, and molecular dynamics simulations.

Summary
In recent years the sensitivity of enhanced Raman scattering has reached hitherto unprecedented values permitting even single molecule analysis. Giant enhancements paved the way for single molecule surface-enhanced Raman spectroscopy. Developments in tip-enhanced Raman spectroscopy, in particular approaches towards single molecule detection in both in air and in ultrahigh vacuum (UHV), followed a similar route providing not only a high sensitivity but also a spatial resolution on the nanometer scale.
