<p>Hi, </p>
<p><br>
</p>
<p>Thank you for your very helpful and detailed response Lorenzo. We have now been able to produce nice Raman spectra for our system.</p>
<p><br>
</p>
<p>On a related topic, we were interested in how the choice of supercell size might influence the vibrational modes we calculate. For instance, looking at a the smallest repeatable unit of our system naturally yields fewer vibrational modes than simulating
a cell of 2 or 3 times the size. We were wondering whether allowing the extra freedom associated with a larger cell might actually map worse onto experimental results? </p>
<p><br>
</p>
<p>Thanks again,</p>
