Liquid water is considered the cornerstone of life and has many extraordinary physical and biochemical properties. The hydrogen bond network of liquid water is widely recognized to play a crucial role in these properties. Due to the complexity of intermolecular interactions and the large spectral overlap of relevant modes, the study of hydrogen bond dynamics is challenging. In recent years, exciting liquids resonantly with terahertz (THz) waves provides a new perspective for exploring the transient evolution of low-frequency molecular motion. However, water has a large absorption coefficient in the THz band, the application of the THz-induced Kerr effect technique in hydrogen bond dynamic research has remained challenging.
