1H Homonuclear NMR (COSY, TOCSY, NOESY)
- Homonuclear 2D experiments acquire 2D spectra as F2(1H) - F1(1H) where F2 is the direct detection dimension for 1H and F1 is the indirect detection dimension.
- Experiments for proteins require water suppression but experiments for small organic molecules may not need it. Different versions of sequences for the same experiment are presented with or without solvent suppresions.
- Main solvent suppression techniques presented are; presaturation (pr), watergate with water-selective soft pulses (wg), and watergate with 3-9-19 pulse schemes (19).
