✦ Synopsis
In a spin system that exhibits multi-exponential longitudinal relaxation, multiplequantum coherence may be created by a n/2 pulse acting on a state of partially recovered polarization. This, together with recently discovered violations of COherence-transfer selection rules through multiexponential transverse relaxation, allows one to design a new twodimensional NMR method. The shapes of the peaks situated on the skew diagonal of the spectrum are determined by longitudinal and transverse relaxation functions along the wt and wp axes, respectively.
