<div dir="ltr">Hello Every one<div>I am a beginner of DFT calculations. I need to calculate the vibrational frequencies of TiO2. </div><div>From Q-E website, I have come to know that Q-E offers DFT+U calculation for ionic relaxation but not for vibrational frequency (phonons).</div><div>can any one explain what will be difference in the absolute magnitude of vibrational modes if one calculate the frequencies with and with without U correction. <br clear="all"><div><br></div>-- <br><div class="gmail_signature"><div dir="ltr">Best Regards<div>Adnan</div><div>UFJF.
