Sentence examples for assignment of proton from inspiring English sources

Assignment of proton signals was achieved through two-dimensional (2D) experiments: homonuclear 1H-1H correlation spectroscopy (COSY), total correlation spectroscopy (TOCSY), nuclear Overhauser enhancement spectroscopy (NOESY), and heteronuclear 1H-13C heteronuclear single-quantum correlation (HSQC), and heteronuclear multiple bond coherence (HMBC).

CH5 H41/42 cross-peaks in NOESY spectra differentiated C from U in the TOCSY spectra and initiated assignment of proton resonances.
