Vibrational Sum Frequency Generation (SFG) Spectra offer the possibility of considerable structure information concerning interfaces and surfaces. However the connection of the experimental results to the underlying molecular level interpretation. In this talk, we will describe the first of two (related) theories for SFG, an energy representation approach. Key ingredients and assumptions of the approach will be recounted, and applications to the water-air surface will be described.
