Research Abstract

ln order to find a practical application of terahettz spectroscopy, we conducted a spectral analysis of the aqueous solution. We could confirm that analytical method such as chemometrix is beneflcial technique to estimate concelltration of solute in a simple aqueous solution. It was also successful in monitoring the change in hydration of the polymer and water molecules. Additionally, we concluded when measuring the changc of the solute in spectroscopy with a sllicon rod, we need temperature correction method
