This $535,000 National Science Foundation (NSF) Division of Chemistry Project Grant, awarded under the Mathematical and Physical Sciences Program (CFDA 47.049), supports a collaborative research project at the California Institute of Technology (Caltech) to develop advanced ultrafast terahertz (THz) spectroscopy techniques and apply them to study the intermolecular forces and dynamics in liquids, especially liquid water and water mixtures. The project aims to overcome technical challenges in generating tailored sub-picosecond THz pulses to enable direct probes of hydrogen bonding and other intermolecular interactions. The research findings could lead to new THz-based methodologies with applications in areas like sustainable energy, telecommunications, and national security. The project also provides an interdisciplinary research environment for graduate and undergraduate students, including those from nearby minority-serving institutions.
