Basics of two-dimensional NMR
The introduction of pulse-Fourier transform NMR established a permanent link between the time-domain “physics” phenomena and the continuous-wave “chemistry” procedures. The principles of time-domain NMR are expressed most compactly in Liouville space, meaning the space of all orthogonal operators for the spin system. A general two-dimensional NMR pulse sequence is constructed by inserting an evolution interval and a mixing sequence into a 1D pulse sequence. In the majority of NMR experiments, the nuclear magnetization is detected by the Faraday induction of an electrical signal in a coil of wire close to the NMR sample, induced by precessing transverse magnetization. One of the most powerful and versatile principles of 2D NMR is that it allows the experimental determination of correlations in the NMR behavior of the nuclear spin system at two different points in time.

Abstract
The introduction of pulse-Fourier transform NMR established a permanent link between the time-domain “physics” phenomena and the continuous-wave “chemistry” procedures. The principles of time-domain NMR are expressed most compactly in Liouville space, meaning the space of all orthogonal operators for the spin system. A general two-dimensional NMR pulse sequence is constructed by inserting an evolution interval and a mixing sequence into a 1D pulse sequence. In the majority of NMR experiments, the nuclear magnetization is detected by the Faraday induction of an electrical signal in a coil of wire close to the NMR sample, induced by precessing transverse magnetization. One of the most powerful and versatile principles of 2D NMR is that it allows the experimental determination of correlations in the NMR behavior of the nuclear spin system at two different points in time.
