The structure analysis of liquid water by the infrared-absorbing analysis method is difficult. As a symmetry stretching vibration and an anti-symmetry stretching vibration overlap by the Fermi resonance and the coupling. The Deconvolution processing can separate the spectrum which overlapped. Then the spectrum of liquid water was separated, and was examined about the possession of the peak. As results, it has been indicated to remove the Fermi resonance from the spectrum by temperature changes. Moreover, it was proved that the stretching vibration band composed of more than 2 peaks. It is. as for H_2O. the plural and D_2O spectra consist of four peaks. From the above thing, the Deconvolution processing spectrum was shown clearly the liquid water structure change. Moreover, a liquid structure is analyzed by the stretching vibration bands which divided, and it considers that two explanations can interpret it. Therefore, availability of Deconvolution processing for a liquid structure analysis law can be confirmed.
