Liquid interface experiments

Second harmonic generation is a nonlinear optical process, in which photons interacting with a nonlinear material are effectively "combined" to form new photons with twice the energy, and therefore twice the frequency and half the wavelength of the initial photons. It is a special case of Sum frequency generation.

This technique has been used to study the interface between two mediums, in this work the liquid/air interface. A number of organic compounds have been investigate, determining the surface orientation of the molecoles and the Gibbs free energy of adsorption at the interface.
