Manually changing the charge of an atom
You may click on any atom group whose charges you think most appropriate to change. The atom group circled in red will be used as an example.
Once you have clicked on an atom group, its information will appear in a window to the left.
This particular atom group consists of a carbon and a hydrogen atom. To modify the charge of a specific atom within the selected atom group, click the ‘Edit’ button of that atom. Here, the charge of the hydrogen atom is being modified.
You can then type a new charge into the input box.
Click ‘Apply’ to confirm the change.
