[xcrysden] Difference charge density

[Peram sreenivasa reddy]

Dear Xcrysden,

                   Recently I am trying to analyze the Difference charge
density plots. I got 2D plot. But i am troubling to analyze the plots. By
using color thermo meter what can we conformed?. i.e if the value is
negative means what? and positive means means what?. Is it indicate flow of
charge from one atom to another atom from low electro negativity to high
electro negativity?.

Thank you in advance......
