Sum frequency generation, calculation of absolute intensities, comparison with experiments, and two-field relaxation-based derivation [Chemistry]

The experimental sum frequency generation (SFG) spectrum is the response to an infrared pulse and a visible pulse and is a highly surface-sensitive technique. We treat the surface dangling OH bonds at the air/water interface and focus on the absolute SFG intensities for the resonant terms, a focus that permits...
