Pro Tips for Choosing Your Topic

• Focus on a specific 'mechanism' or 'interaction' rather than a broad field to ensure your analysis remains technical.
• Always include quantitative data or spectral evidence (NMR, IR, UV-Vis) to support your chemical arguments.
• Check the 'Supporting Information' of primary journal articles for the experimental details that often provide the best analytical insights.
• Use the 'ACS Style Guide' for all chemical nomenclature and citation formatting to maintain professional standards.
• Differentiate between 'correlation' and 'causation' when analyzing reaction rates or thermodynamic trends.
