Prof. Jeremy Johnson from the Dept. of Chemistry and Biochemistry at Brigham Young University, will present "Distinguishing Nonlinear Terahertz Excitation Pathways with 2-Dimensional Spectroscopy."
Abstract: High-field terahertz (THz) spectroscopy is enabling the ultrafast study and control of matter in new and exciting ways. However, when intense electromagnetic pulses are used in any kind of pump-probe spectroscopy, several nonlinear excitation pathways can result, leading to scenarios that required the development of multi-dimensional spectroscopies to illuminate the observed dynamics. I’ll describe a clear example where 2-dimensional (2D) THz vibrational spectroscopy is needed to distinguish between nonlinear-excitation pathways in crystalline CdWO4.
