Paper Abstract

A single molecular layer is generally sufficient to produce observable optical second harmonic generation (SHG). Furthermore, the selection rules governing this process make the SHG from a single monolayer often stronger than that from the medium supporting the monolayer. We have studied SHG from various Langmuir-type monolayers (i.e. monolayers spread on a water surface) in the following contexts: (1) Study of chemical reactions (e.g. polymerization) and two-dimensional phase transitions in molecular monolayers on water. (2) Development of a new technique to evaluate optical nonlinear coefficients of organic molecules, and their relationship to the molecular structure.
