<div>Hello,</div>
<div><br>
</div>
<div>I would like to run an geometry optimization calculation using ADC(2). I have so far tested several input parameters but still could not make it run. Part of my input file now reads: </div>
<div><br>
</div>
<div>hf</div>
<div>local,orbrel=1</div>
<div>forces,varsav</div>
<div>lt-df-ladc(2)</div>
<div>eom,-4.1,ADC2=1,trans=1,tranes=2.1-4.1,propes=2.1-4.1,GSONLY=0,GRADSTATE=2.1</div>
<div><br>
</div>
<div>and the calculation crashed with the error message:</div>
<div><br>
</div>
<div> entering iget_cis_oldvec</div>
<div> ? Error</div>
<div> ? iget_cis_oldvec</div>
<div> ? The problem occurs in Follow_Grad</div>
<div><br>
</div>
<div>So how can I successfully run an analytical ADC(2) excited state geometry optimization? Many thanks.<br>
</div>

<div>Best,<br>
