<p class="MsoNormal">Dear Molpro experts,</p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">This is my third inquiry into a problem I have
encountered.<span style=""> </span>Please somebody give me
some help this time. <span style=""> </span>This is what
happens:<span style=""> </span>I am trying to compute at the
CI level the dipole transition moments between the fourth [2] Sigma state of
the AlH+ ion and the lower three states in the region from 1.1 to 30.0 Bohr.<span style="">
</span>I start at the state averaged MCSCF level with five states.<span style=""> </span>At long <span style=""> </span>Al-H distances the potential and the
transition moments appear quite normal.<span style=""> </span>However,
at short distances of less than four Bohr, higher states replace the fourth and
fifth states of the calculation (the first three are not affected) and so the
potentials and the resulting moments are erratic and useless.<span style=""> </span>If I include more than five states in the
calculation, I need to increase the “nstati” parameter and then I run into the
ARMCI segmentation violation error with status=11.<span style=""> </span>Also, some dipole transition moments do not
appear at all in the relevant lists that follow the energy results.<span style=""> </span>Given that the region in question is most
important for some collision calculations I would appreciate any help from the
users and the experts.<span style=""> </span>Why higher states
enter the calculation?<span style=""> </span>It happens during
the convergence iterations.<span style=""> </span></p>
<p class="MsoNormal">The command file is attached.</p>
