Sequential walking Sequential walking Sequential walking is a technique that can be used to solve various 2D NMR spectra. In a 2D experiment, cross peaks must be correlated to the correct nuclei. Using sequential walking, the correct nuclei can be assigned to their crosspeaks. The assigned crosspeaks can give valuable information such as spatial interactions between nuclei. In a NOESY of DNA, for example, each nucleotide has a different chemical shift associated with it. In general, A's are more downstream, T's are more upstream, and C's and G's are intermediate. Each nucleotide has protons on the deoxyribose sugar, which can be assigned
