Dear CCL'ers, I am using Gaussian-98. I want to calculating the 5d-3d charge transfer integral for Cu-Gd. Can I do this calculated using GAUSSIAN-98? and How can I do? Thanks a lot in advance! I am looking forward to your replies. Best regards, Hulya KARA __________________________________________________ Do You Yahoo!? Get email at your own domain with Yahoo!
