Abstract :
In order to analyze the variations of water clusters in insulating liquids, the infrared spectra of the liquids were measured at several different temperatures under a electric field by the Fourier-transform infrared method. The conductivities were measured at the same time to evaluate the effect of the variations on the conduction phenomena. The spectra of water clusters in dioctyle-phthalate (DOP) are shown to change in the range from room temperature to 130°C. It is seen that dimer and trimer decrease with increase of the spectra in the range 3200-2600 cm-1. These variations are understood as the transformation of dimer and trimer to the spectra at 3200-2600 cm-1 ; therefore it is considered that the spectrum at 3200-2600 cm-1 corresponds to one state of water in DOP
