<p>Hello,</p>
<p><br>
</p>
<p> I have re-run a Phonon calculation for a charged cluster that was done using version 5.1 with version 7.2 and the results are completely different; there is a large positive shift in the frequencies. Can somebody tell me what was done differently in 5.1
for charged cells ?</p>
