Hello Sagnik,<div><br /></div><div>I am not an expert, but I might be able to help. It seems like you want to calculate the mean atomic dipole moment with your equation "magnitude of dipole moment=SQRT( (summation of x-component)^2 + (summation of y-component)^2 + (summation of z_component)^2)) / number of atoms", right? Did you also calculate the mean atomic dipole moment from Wannier localization in the same way? By how much do your results from Voronoi integration differ from the results from Wannier localization?</div><div><br /></div><div>Best wishes, </div><div>Nathalie Smith<br /><br /></div><div class="gmail_quote"><div dir="auto" class="gmail_attr">Sagnik Mukhopadhyay schrieb am Montag, 26.

was running a simulation for a system with Au-H2O, where I was
calculating the dipole moment of the Au, H2O and overall system using
Voronoi integration. In the ".voronoi" file there is information about
charge, position, dipole moment vector, quadrupole moment tensor
(component wise) etc. To calculate the dipole moment I was using the
formula: magnitude of dipole moment=SQRT( (summation of x-component)^2 +
(summation of y-component)^2 + (summation of z_component)^2)) / number
of atoms. After using this formula the dipole I got is different from
the one obtained from Wannier localization. Can somebody confirm if this is the formula to calculate the dipole moment using Voronoi integration?</div><div>Thanks in advance.</div><div><br></div><div>Regards</div>Sagnik</blockquote></div>
