Hi, <br>The isotope effect only has impact on PHONON calculation. In this situation , you need to specify different atomic mass for the different isotopes.<br>Please have a look at INPUT_PH.<br><br>Hopt it helps<br><br>Regards,<br>

Dear PWSCF users,<br>
<br>
I am trying to consider effect of isotope. How can I get the PP of isotope (ex. O(16) and O(17))?<br>
<br>
