Measurement method of
nuclear magnetic resonance spectroscopy in which data are collected in two
time domains: acquisition of the
free induction decay (
\(t_{2}\)) and a successively incremented delay (
\(t_{1}\)).
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).
