High-resolution Fabry-Perot observations have been made to determine the velocity structure of five PNe and to subsequently relate the observations to the morphology of the objects. New kinematic data on one of these PNe, NGC 5882, are given and existing observations in other cases are supplemented. The effect of aperture size on expansion velocity in NGC 5882 is investigated. An attempt is made quantitatively to account for the unusual triple-peaked line profile observed in the bipolar nebula NGC 2818.
