In this paper,attenuated total reflectance infrared spectroscopy is used to study the influence of static magnetic field on ethanol and solution of water and ethanol.Experiments show the spectra of ethanol are obviously changed under action of static magnetic field.It is found that in region of 400~4000cm-1,not only the absorbance is increasing with the increasing of the time ethanol processed by magnetic field,but new absorbing bands appear more clearly at 1031,1054,2052,2075,2842 and 2865 cm-1 with the time ethanol processed by magnetic field.It is also found the spectra of the solution of water and ethanol are changed after it is processed by static magnetic field.In conclusion,exist of static magnetic field makes the hydrogen bonding between ethanol molecules and hydrogen bonding between ethanol molecules and water molecules and influence the vibration of O-H,-CH2 and -CH3.
