The theory of electron tunneling through single molecules is introduced with special focus on periodic molecules, where the problem is simply understood in terms of complex wave-vector Bloch states. The molecule length dependence of the current, the Fermi level alignment problem, barrier traversal times, and other important aspects of single molecule transport in general come in to play in this context. The Landauer formalism is a framework for more quantitative treatments of more general structures and a brief introduction to this subject is also given.
