<p>Dear QE users and developers,</p>
<p><br>
</p>
<p>I was wondering if you could elaborate on possibility of modeling absorption spectra of inorganic materials/molecules using TDDFPT module of QE. There are many discussion regarding insufficiency of TDDFT itself to model charge transfer and corresponding
issues with excitation. on top of that, when I went through excitation papers I have found out, most excitation papers are done on organic molecules such as methane and etc. This is also true in case of QE TDDFPT examples.
<br>
</p>
<p>Hence, is it possible to model absorption spectra of complex inorganic molecule such as Y2SiO5 with TDDFPT module or in the larger context TDDFT itself?</p>
<p><br>
</p>
<p>Thanks in advance,</p>
<p>With kind regards,</p>
