Logical flow: Great science poorly presented is diminished. A complete talk usually begins with background, leading into the presentation of pertinent results, and followed by the important conclusions that can be drawn from those results. Background information must give context for the work. Why is this work important to the chemical community or the greater world? What problem(s) is this work addressing? It should describe any experimental techniques or methods that might not be common to the experiences of a typical chemist or your particular audience. Pertinent results should be presented in an organized manner, including clear spectra or summary tables. A running outline is one way to maintain organization during a talk. Plan smooth transitions between a slide just presented and the next one about to appear.
