A more detailed analysis at TB coupling

Generalisations concerning the design of bridges displaying enhanced coupling due to constructive interference effects are detailed elsewhere.41,123 

As mentioned earlier, KT/3-21G calculations offer a simple computational method for reliably estimating both the distance dependence and the strength of the electronic coupling element for ET in a variety of systems.39,83 In this context, one also requires a method for analysing and dissecting intra-bridge orbital interactions, and several elegant treatments are available.39,42-45,84,85,89,125-140
