Abstract: By fitting model values of physical quantities for deuterated SQA crystal in theoretically derived expression for AFE mode frequency, dielectric entrant and loss tangent in my earlier paper [<i>Indian J Pure &amp; Appl Phys, </i>47 (2009) 119] temperature dependence of these quantities have been calculated and compared with experimental data of Maier <i>et al., </i><i style="">Phys Status Solidi (b), </i>89 (1978) 578 and Semmingsen, D<i style="">, Acta Chem Scand</i>, 27 (1977) 3961, which show a good agreement.
