Web1 H-1 H COSY (COrrelated SpectroscopY) is a useful method for determining which signals arise from neighboring protons (usually up to four bonds). Correlations appear when … WebNote: 13C chemical shift predictions can be quite useful for making (tentative) assignments. These should be confirmed with prior (literature) knowledge when available, but data is always best, made using spectra such as COSY and HSQC/HMBC. d) COSY spectra are assigned by clicking the atom, then the center of diagonal peak to be assigned.
