Maxwell-Wagner absorption

C <.0.222 where AHW =0 (Figure 3-a) and AH,] >AH (Figure 5) liquid samples exhibit at 20°C a "Maxwell-Wagner" absorption centered at a frequency higher than 100 MHz, (Figure 2,curve 1-F) the permittivity low temperature dependence follows a flat trend (Figure 1-a, curves F). 

The low frequency absorption II originates from the Maxwell-Wagner effect already observed in dehydrated X-type zeolites (8). In the presence of water the enhanced cationic mobility intensifies this effect. This interpretation disagrees with that of Matron et al. (10). They ascribed their low frequency a-process to cations on site I and site II. This is improbable in view of the correspondence with the Maxwell-Wagner effect in dehydrated X-type zeolites, observed by us (8).
