<div class="gmail_quote">Dear Molpro authors and users,<br><br>I wanted to compute the optimized structure of a given molecule in its ground and excited states, and then compute its frequencies, using CASPT2 ( rhf -> multi -> rs2 ) method. I am getting an error stating "Inconsistent occupation in mcscf and rs2". I have tried to switch off the symmetry, but was of no use either. The input and output are given below...<br>

? Error<br> ? Inconsistent occupation<br> ? The problem occurs in check_rs2occ<br><br> ERROR EXIT<br><br>Thank you, and looking forward to your suggestions.<br><font color="#888888"><br>Pradeep Kumar Gurunathan,<br>Summer Intern Fellow,<br>
