I have determined graphical behavior of refractive index, extinction coefficient, reflectivity, energy loss function as a function of frequency. when I move to absorption coefficient, it needs specific wavelength <img src="http://www.pveducation.org/sites/default/files/PVCDROM/PN-Junction/Equations/image050.png" alt="extinction absorption coefficient equation" class="">. Can anyone guide me in this path. I just want to know how to take the value of wavelength in the expression.</div><div>Thanks in advance.</div></div></div><div class="gmail_extra"><br><div class="gmail_quote">On Mon, Jun 15, 2015 at 4:55 PM, Amreen Bano <span dir="ltr"><<a href="mailto:banoamreen.7@gmail.com" target="_blank">banoamreen.7@gmail.com</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div dir="ltr"><div><span style="color:rgb(80,0,80);font-size:12.8000001907349px">Respected Sir/Mam,</span></div><div><span style="color:rgb(80,0,80);font-size:12.8000001907349px">I am working on optical properties.</span></div><span style="color:rgb(80,0,80);font-size:12.8000001907349px"><div><span style="font-size:12.8000001907349px">I have run dynmat.x file and obtained the output below:</span><br></div></span><br style="color:rgb(80,0,80);font-size:12.8000001907349px"><span style="color:rgb(80,0,80);font-size:12.8000001907349px"># mode [cm-1] [THz] IR Raman depol.fact</span><br style="color:rgb(80,0,80);font-size:12.8000001907349px"><span style="color:rgb(80,0,80);font-size:12.8000001907349px"> 1 -487.60 -14.6178 37.7287 277.8609 0.6461</span><br style="color:rgb(80,0,80);font-size:12.8000001907349px"><span style="color:rgb(80,0,80);font-size:12.8000001907349px"> 2 -0.00 -0.0000 0.0000 334597.4170 0.7437</span><br style="color:rgb(80,0,80);font-size:12.8000001907349px"><span style="color:rgb(80,0,80);font-size:12.8000001907349px"> 3 -0.00 -0.0000 0.0000 8113.2975 0.7291</span><br style="color:rgb(80,0,80);font-size:12.8000001907349px"><span style="color:rgb(80,0,80);font-size:12.8000001907349px"> 4 -0.00 -0.0000 0.0000 25779.9020 0.7455</span><br style="color:rgb(80,0,80);font-size:12.8000001907349px"><span style="color:rgb(80,0,80);font-size:12.8000001907349px"> 5 0.00 0.0000 0.0000 6417.8442 0.6634</span><br style="color:rgb(80,0,80);font-size:12.8000001907349px"><span style="color:rgb(80,0,80);font-size:12.8000001907349px"> 6 0.00 0.0000 0.0000 171.7054 0.6246</span><br style="color:rgb(80,0,80);font-size:12.8000001907349px"><span style="color:rgb(80,0,80);font-size:12.8000001907349px"> 7 0.00 0.0000 0.0000 29050.2808 0.7489</span><br style="color:rgb(80,0,80);font-size:12.8000001907349px"><span style="color:rgb(80,0,80);font-size:12.8000001907349px"> 8 56.80 1.7028 4.4068 273118.7875 0.7446</span><br style="color:rgb(80,0,80);font-size:12.8000001907349px"><span style="color:rgb(80,0,80);font-size:12.8000001907349px"> 9 160.49 4.8115 11.3630 55305.2885 0.7395</span><br style="color:rgb(80,0,80);font-size:12.8000001907349px"><span style="color:rgb(80,0,80);font-size:12.8000001907349px"> 10 223.34 6.6954 3.8373 91527.1127 0.7438</span><br style="color:rgb(80,0,80);font-size:12.8000001907349px"><span style="color:rgb(80,0,80);font-size:12.8000001907349px"> 11 327.82 9.8277 2.9918 21597.6373 0.7373</span><br style="color:rgb(80,0,80);font-size:12.8000001907349px"><span style="color:rgb(80,0,80);font-size:12.8000001907349px"> 12 351.66 10.5424 1.9769 1081889.8225 0.7431</span><br style="color:rgb(80,0,80);font-size:12.8000001907349px"><span style="color:rgb(80,0,80);font-size:12.8000001907349px"> 13 555.84 16.6637 3.8963 13013.8834 0.2450</span><br style="color:rgb(80,0,80);font-size:12.8000001907349px"><span style="color:rgb(80,0,80);font-size:12.8000001907349px"> 14 748.23 22.4315 9.1009 3164.2275 0.1576</span><br style="color:rgb(80,0,80);font-size:12.8000001907349px"><span style="color:rgb(80,0,80);font-size:12.8000001907349px"> 15 790.74 23.7059 5.1725 764.0895 0.5078.</span><div>With the 2nd and 5th column i can form raman spectra, but output contains very few values which is giving abnormal plot.<br style="color:rgb(80,0,80);font-size:12.8000001907349px"><font color="#500050"><span style="font-size:12.8000001907349px">how can i plot a correct and smooth plot for raman spectra.</span></font><br style="color:rgb(80,0,80);font-size:12.8000001907349px"><span style="color:rgb(80,0,80);font-size:12.8000001907349px">please suggest me the correct path.</span><span class="HOEnZb"><font color="#888888"><br clear="all"><div><br></div>-- <br><div><div dir="ltr"><div style="font-family:arial;font-size:small">Amreen Bano</div><div style="font-family:arial;font-size:small">Department of Physics,</div><div style="font-family:arial;font-size:small">Barkatullah University,</div><div style="font-family:arial;font-size:small">Bhopal-462 026</div><div style="font-family:arial;font-size:small">INDIA</div><div style="font-family:arial;font-size:small">+91-9993515955</div><div style="font-family:arial;font-size:small"><a href="mailto:banoamreen.7@gmail.com" target="_blank">banoamreen.7@gmail.com</a></div></div></div>
