MUNIN: Application of three-way decomposition to the analysis of heteronuclear NMR relaxation data

MUNIN ((Mu) under bar ltidimensional (N) under bar MR Spectra (In) under bar terpretation), a recently introduced approach exploiting the mathematical concept of three-way decomposition, is proposed for separation and quantitative relaxation measurements of strongly overlapped resonances in sets of heteronuclear two-dimensional spectra that result from typical relaxation experiments. The approach is general and may also be applied to sets of two-dimensional spectra with arbitrary modulation along the third dimension (e.g., J-coupling, diffusion). Here, the method is applied for the analysis of N-15 rotating frame relaxation data.
