Analysis Make NMR and IR assignments directly on your spectra. If you are unable to print the spectra, please make these assignments on a separate sheet of paper. Interpret the spectral data and MP data in the analysis section of your lab notebook. In your discussion, indicate how you deduced the structural identity of your cross-coupled product, and how you unmasked the structural identities of your unknown starting materials.
