1H NMR Spectrum characterization Figure1shows the typical spectra of a whole serum sample obtained with different pulse sequences. The use of different pulse sequences allows to investigate different properties of the samples; spectra obtained with pulse-and-acquire (Fig.1A) is dominated by large ...
