Guidelines for Results & Discussion Section Extracted from “Scientific Papers” in The ACS Style Guide, Coghill, A.M. and Garson, L.R., eds. (American Chemical Society: Washington, DC, 2006), 17-26 Results. Summarize the data collected and their statistical treatment. Include only relevant data, but give sufficient detail to justify the conclusions. Use equations, figures, and tables only where necessary for clarity and brevity. Extensive but relevant data should be included in supporting information. Discussion. The purpose of the discussion is to interpret and compare the results. Be objective; point out the features and limit-ations of the work. Relate your results to current knowledge in the field and to the original purpose in undertaking the project: Was the problem resolved? What has been contributed? Briefly state the logical implica-tions of the results. Suggest further study or applications if warranted.
