<p> I am trying to do vibrational analysis for gas phase system. I am
following the tutorial "Calculating Vibrational Spectra from Molecular
Dynamics". Initially i have done massive equilibration of a single methanol
system for 6000 steps. After that i use the following example CP2k input file
to simulating a trajectory with wannier centers for 60000 steps. Then, I calculated
the IR spectra with <a href="http://methanol_wannier.xyz" target="_blank" rel="nofollow" data-saferedirecturl="https://www.google.com/url?hl=en&q=http://methanol_wannier.xyz&source=gmail&ust=1645707627987000&usg=AFQjCNE4oK816V9ogYDzgEw1IX_7VKvxYw">methanol_wannier.xyz</a> file using Travis software.
Unfortunately, I don’t get a good IR spectrum because of it doesn’t show peaks
at 200, 1000, 1500 and 3700 cm-1 and it has very noise. Would you please guide me why I don’t get
a good IR spectrum?</p>
<p><br></p><p>Here i am
attaching my IR spectrum and
the input files of massive equilibration and the wannier center for a single methanol.</p>
<p>Please help me
on this.</p><p>Thanks.</p><p><img alt="IR.png" width="534px" height="322px" src="https://groups.google.com/group/cp2k/attach/9563cce89867/IR.png?part=0.1&view=1"><br></p></blockquote></div>
