Summary, etc. <strong>Double relaxation times <em><img src="http://nopr.niscair.res.in/image/spc_char/tow.gif" border="0" alt="" /></em><sub>2</sub> and <em><img src="http://nopr.niscair.res.in/image/spc_char/tow.gif" border="0" alt="" /></em><sub>1</sub> due to whole molecular rotation and the flexible parts of the binary (<em>jk</em>) polar mixture of<em> p-</em>cresol,<em> p-</em>chlorophenol, 2,4 dichlorophenol and<em> p-</em>bromophenol with methyl methacrylate (MMA) or ethyl methacrylate (EMA) were estimated under 9.37 GH<sub>Z</sub> electric field dissolved in dilute CCl<sub>4</sub> solution at 35°C using high frequency susceptibility data <em><em><img src="http://nopr.niscair.res.in/image/spc_char/lembda.gif" border="0" alt="" /><sub>ijk</sub></em></em>’s for different weight fractions <em>w<sub>jk</sub></em>’s. Six systems out of eight exhibit <em><img src="http://nopr.niscair.res.in/image/spc_char/tow.gif" border="0" alt="" /></em><sub>2</sub>, <em><img src="http://nopr.niscair.res.in/image/spc_char/tow.gif" border="0" alt="" /></em><sub>1</sub>; <em>c</em><sub>2</sub>, <em>c</em><sub>1</sub> and <em>μ</em><sub>2</sub>, <em>μ</em><sub>1</sub>, respectively. The estimated <em><img src="http://nopr.niscair.res.in/image/spc_char/tow.gif" border="0" alt="" /></em><sub>2</sub>’s and <em>μ</em><sub>2</sub>’s agree well with the measured and reported values indicating the whole rotation of binary polar mixture under high frequency electric field. Solute-solute and solute-solvent molecular formation through H-bonding are ascertained from <em>μ</em><sub>av</sub> – <em>x<sub>j</sub></em> curves for 0.5 mole fraction <em>x<sub>j </sub></em>of acrylic ester. The associational aspects are taken into consideration in <em>μ</em><sub>theo</sub> from the stand point of inductive, mesomeric and electromeric effects within the polar groups of the molecules. Static <em>μ</em><sub>0</sub>’s are calculated and compared with the reported values also.</strong>
