Abstract :
The state of water cluster in dielectric liquid was observed by FT-IR and relation between the ratio of cluster and conductivity was discussed. In this experiment, an ester compound with several length of alkyl chain was used. From the results, dissolved water molecules in dielectric liquid form some types of cluster and the composition of each cluster depends on the length of alkyl chain. It appeared that the conductivity of liquid depends on the ratio of clusters. The ratio of dimer and trimer in the liquid especially increases conductivity
