Is anyone familiar with semi-empirical calculations of CT interactions in viologens?

I am interested in making a theoretical calculation of a charge transfer (CT) interaction between dicationic 4,4'-bipyridinium ("viologen") moiety as charge acceptor and nucleobases (i.e. thymine...

How to calculate energy of H-Bonds formation in DNA double helix from hyperchromic effect at 260 nm?

I run a "Tm" (melting point DNA) experiment which consists in heating a sample of DNA double strand in buffer solution from 20°C to 85°C with a constant heat rate. Simultaneously, I monitor the...
