R.: Two-dimensional chemical exchange and cross-relaxation spectroscopy of coupled nuclear spins. In: Journal of Magnetic Resonance Nr. 2, Jg. 43(1981), S. 259-281.http://hdl.handle.net/2003/2531810.17877/DE290R-3443The features of two-dimensional cross-relaxation and chemical exchange spectroscopy of coupled spins are investigated theoretically and by experiment. It is shown that spin-spin couplings can lead to J cross-peaks in analogy to cross-peaks in two-dimensional autocorrelated spectroscopy. They reflect a coherent magnetization transfer in contrast to the incoherent processes responsible for cross-relaxation and for chemical exchange. Possibilities of selectively suppressing J cross-peaks are discussed.enElsevier53010.1016/0022-2364(81)90037-8article (journal)
