Description

<p>Registration s are now closed The purpose of the tutorial is to introduce the computation of NMR spectra to the participants. After the tutorial they will be able to run calculations of their interest. We shall use the DFT-GIPAW package implemented in the code PWSCF in the Quantum Espresso package.
<ul>
<li>Short review of the theoretical background of DFT-GIPAW</li>
<li>Basics of experimental NMR and introduction to the measurement of NMR parameters</li>
<li>Use of the PWSCF package and the main steps for performing reliable NMR calculations</li>
<li>How to compare DFT-GIPAW results with experimental values.</li>
</ul>
