<p>Dear users,</p>
<p>I have calculated the normal modes around Gamma point of a compound using ph.x.</p>
<p>All my modes are Raman active. I have followed example15 in the tutorials of the</p>
<p>release q-e-qe-6.7MaX-Release.tar.gz.</p>
<p>After completing the phonon calculations I run dynmat.x.</p>
<p>Then I extract and plot the Raman frequecies and intensities</p>
<p>using the following two commands.</p>
<p>awk ‘NR==1,/mode/{next}/DYNMAT/,NR==0{next}{print}’ si.dm.out > plotdata_si.dat <br><br>plot ‘plotdata_si.dat’ u ($2):($3) title ‘ si-RAMAN’ w i lw 2</p>
<p>I want to clarify if this is the correct way to extract the Raman intensities. If not,</p>
<p>where can I find how to do this in an appropriate way.</p>
<p>Thanking you,</p>
<p>Banhi Chatterjee</p>
