ule, JMAX is the maximum rotational quantum
number <b>minus 1/2</b>; so that the allowed channel rotational angular momenta run from 1/2 to JMAX+1/2.

<p>IGU:  inversion symmetry of states included in expansion.
<ul>
IGU = +1 for <i>gerade</i> states<br>
IGU = -1 for <i>ungerade</i> states<br>
 <img src=cautionsmall.gif> For heteronuclear
molecules (<a href=ihomo.html>IHOMO</a> = .false), IGU is ignored but
should be set to +1
