TOCSY - Total Correlation SpectroscopY

An experiment where chemical shift (recorded in one dimension, usually - directly detected) of a given nucleus A is correlated with chemical shifts (recorded in the second dimension) of all nuclei of particular kind that are within the spin system of the atom A. So for example in protein NMR this experiment allow to get correlation between all protons of an amino acid.

HOHAHA (Homonuclear Hartmann Hahn) is a synonym of TOCSY
