Abstract :
Recently we used kinetic terahertz absorption (KITA) spectroscopy to investigate hydration dynamics during enzymatic hydrolysis. In order to extend KITA studies by phase and frequency information, we set up a dual-mode THz time domain spectrometer (TDS) that can be run either in asynchronous optical sampling (ASOPS) or conventional TDS mode.
