A stable and high-speed transmission infrared spectroscopy system for in-situ observation of chemical reaction in the water was fabricated. In-situ transmission infrared spectroscopy of hydroxylation of metallic film and subsequent dehydration processes were observed. Systematic change of absorbance in the three phases and the supercritical phase of the water were also observed and evaluated their states of the hydrogen bond. Furthermore, absorbance spectra of the adenosine triphosphate solution were observed and identification of the decomposed components was achieved. As a result, it was confirmed that transmission infrared spectroscopy was useful for the evaluation of chemical reaction in the aqueous solution.
