bond length of Carbon bond in graphene using DFT
« on: April 21, 2016, 10:17 »
I would like to ask how to find the bond length of Carbon-Carbon bond in graphene when simulate with DFT. Thank you.

Once your know the atomic positions (cartesian), you may calculate the atom distance between two atoms quickly by the python script.

You can also simply visualize your configuration in the VNL Viewer, and then use the mouse to "hover" over the relevant bond(s). A dialog box will then show you the bond length.

use "Z-matrix" option that appears in the "Coordinate tools" of Builder. click on the two atoms between which you want to calculate the bond length holding ctrl button.
