^1H-NMR spectrum measurement of water and alcohol mixed solution(DEPARTMENT OF APPLIED CHEMISTRY AND BIOCHEMISTRY)

^1H NMR spectrum measurement was carried out on the mixed solution of water and alcohols. The effect of the hydrophobicity of the alcohol molecule for the hydrogen bond structure which water molecule had formed was examined. It was the order of the t-butanol>isopropanol>propanol>ethanol>methanol that the alcohol was low-densified and that it weakens the hydrogen bond between water molecule. The result of reversely intensifying the hydrogen bond was obtained ehylene glycol and glycerin. This seemed to form the hydrogen bond with the water, since it mainly has hydroxyl group
