 sample z axis (z axis of the <a href="frames.html">sample frame</a>) and the molecular z axis ( axis of the <a href="frames.html">molecular frame</a>), and &lambda; is the number specified in <code>Exp.Ordering</code>.
</p>

<p>
Typical values for &lambda; are between about -10 and +10. For negative values, the orientational distribution function P(&beta;) is maximal at &beta; = 90&deg; (preferential orientation of molecular z axis in the sample xy plane), for positive values it is maximal at &beta; = 0&de
