Draw and solve chemistry Hückel molecular models. Calculate the molecular orbitals or the transmission resolvents.Draw and model the pi-system of conjugated molecules at the Hückel level of theory. A Hückel model is a tight-binding model describing the electrons in the pz orbitals of conjugated molecules.
The Hückel method program calculates the molecular orbitals and makes it possible to simulate a molecular junction by calculating the transmission resolvents for your choice of connecting orbitals.
