Abstract :
In order to describe the mechanisms of the effect of water on electrical properties, we study the state of dissolved water which can be analyzed by IR spectroscopy. We investigate the relationship between conduction current in a dielectric liquid and the structure of water clusters formed by hydrogen bonding. The dielectric constant and loss of several kinds of aromatic hydrocarbons are measured and related to electron donor functional groups. Since the hydrogen bonding energy calculated from the IR spectrum is not very different in donor and acceptor groups, the sensitivity of the effect of water on dielectric constant and loss may be caused by the polarization characteristics of the benzene ring
