Inferencing was conducted using either a more specific Type I prompt template, or more general Type II template. Both prompts were effective in enabling LMMs to serve as step wise devices for the analysis of spectra. Type I -Prompts A and C: Provide the chemical structure with annotated substituents based on the spectra in the image. Include all relevant information that was used to obtain your structure. Type II -Prompt B: Interpret information one step at a time, creating a molecule name at the end based on your findings.
