Abstract
The electric conductivity has been measured over a wide range of temperatures including phase transition temperatures of selenous acid and its transition metal selenites. The effect of hydrogen bonding formation of the crystal structure, as well as, the ion pair formation on the conduction mechanism in the low and high temperature regions was visualized using infrared spectra. The values of thermal activation energies obtained from the electrical conductivity measurements indicate that selenous acid at measuring temperatures and the transition metal selenites at high temperatures behave like semiconducting materials. The transfer of protons along the lines of hydrogen bonds via removal of water molecules during dehydration, and ion pair formation was considered to be the main source participating in the conduction processes.
