Measurement method of nuclear magnetic resonance spectroscopy in which data are collected in two time domains: acquisition of the free induction decay (t2) and a successively incremented delay (t1).

Note: The resulting data matrix is subjected to two successive Fourier transforms to produce a spectrum with two frequency axes, usually either chemical shift/chemical shift (correlation spectroscopy) or chemical shift/J-coupling (see J-resolved spectroscopy).
