[Wien] How to select the isovalue of isosurface ?

[钟国华]

Dear all,

Merry Christmas!

As using the xcrysden to plot the 3D charge density, the isovalue of
isosurface is adjustive. Would you please tell me how to select the
isovalue? What determines this isovalue ? Whether is the selection of
isovalue related to the covalent or ionic interaction?

Thanks for any helps!

Best Wishes!
Yours sincerely,
Zhong
