ET_COUPLING

[Ali]

Dear CP2K Users,

I had a question on the usage of ET_COUPLING in the properties
section. My understanding is that through the use of the DDAP
restraint on the charges, lets say I have a system of net charge -1. I
can then restraint 10 atoms in the system to have a total charge of
-0.5 and the other 10 atoms to have a total charge of -0.5? This will
then yield me et coupling elements? Supposedly I can then vary the
charge to different ratios so that I can "force" and electron transfer
event in the simulation?
