Denote a fragment as excited state in electronic coupling calculation?

Hello, I am trying to calculate electron coupling for a very simple electron trasfer senario that involves one argon ion, one clorine ion and their neural forms. However in this case i would like to specify the argon neutral to be in its excited state, does anyone know how to do this? Thank you in advance!
