| Research Abstract |
Experimental and technical developments for the time-resolved terahertz (THz) spectroscopy on aqueous solutions have been made in this study. First, we performed the steady-state THz spectroscopy on aqueous ionic solutions. As a result, we successfully obtained an experimental evidence for the existence of the ion effects that weaken hydrogen bonding structure in solution, demonstrating the effectiveness of THz spectroscopy for studies on a solution sample. Second, a window-less method using a liquid sheet was developed. This method salves the problem of damaging windows due to a strong pump laser pulse in the conventional method using a solution sample cell. Here, a nozzle which can produce a liquid sheet with controllable thickness from 50 to 120 micrometer has been developed and optimized to THz spectroscopy.
