From: Identification of metabolites from 2D 1H-13C HSQC NMR using peak correlation plots
Real and constructed 1H- 13C HSQC spectra from post-prostatic palpation urine. To the left (a) is one of the 50 recorded 1H-13C HSQC spectra from post-prostatic palpation urine. To the right (b) is a constructed 1H-13C HSQC spectrum, prepared by merging correlation plots from 23 metabolites. Peaks from 7 metabolites with only one 1H-13C HSQC cross-peak are also included. TMAO appears broad due to phase distortion.
