We will discuss several proposed explanations for the switching and negative differential resistance behavior seen in some molecular junctions. It is shown that a proposed polaron model is successful in predicting both hysteresis and NDR behavior, and the model is elaborated with image charge effects and parameters from electronic structure calculations. This model includes the effects of conformational change, charging, and image charge stabilization.
