2.2.b The result of infrared spectroscopic analysis
　The graph shown in Fig.11 is a result of FT-IR on substances those float on the surface.

　Fig.12 is result of FT-IR on floating substances. As the results, we can not find out remarkable absorption peak that identifies C-H types of chemical bonds. There is absorption in nearly 4000 cm^-1 wave numbers that is short of wavelength area on the substance on the glass wall. The fact means that there are hard bonds in the membrane on the grass wall.
