Spectroscopy is the use of electromagnetic radiation to analyze the composition and behavior of matter (e.g., atoms and molecules). Recently developed three dimensional spectroscopy techniques yield spectra with higher resolution and less congestion than in 2D spectroscopy. This project focuses on the development and testing of new nonparametric nonlinear optical processes for generating 3D spectra. According to theory developed by our group, these nonparametric processes should produce peaks that form easily recognizable patterns (e.g., rectangle or triangles). The purpose of this project is to test whether the experimentally observed patterns match the predictions for one of these nonparametric processes (referred to as process 2B) and to further explore the capabilities of techniques based upon this process.
