A strong electr field is used to induce acentric order in a solution of molecules. This results in the product of the the dipole moment &amp;mu; and &amp;beta;. It measures only the component of &amp;beta; along the dopole moment axis.<br /> <br /> This is a useful figure of merit for poled polymer systems but is inappropriate for ionic and non-dipolar chromophores.</div>
