The possibilities for the extension of spectroscopy to two dimensions are discussed. Applications to nuclear magnetic resonance are described. The basic theory of two‐dimensional spectroscopy is developed. Numerous possible applications are mentioned and some of them treated in detail, including the elucidation of energy level diagrams, the observation of multiple quantum transitions, and the recording of high‐resolution spectra in inhomogenous magnetic fields. Experimental results are presented for some simple spin systems.read more

Investigation of exchange processes by two‐dimensional NMR spectroscopy
TL;DR: In this paper, a general technique for the investigation of exchange processes in molecular systems is proposed and demonstrated and applications include the study of chemical exchange, of magnetization transfer by inter-and intramolecular relaxation in liquids, and of spin diffusion and cross-relaxation processes in solids.

MLEV-17-based two-dimensional homonuclear magnetization transfer spectroscopy

TL;DR: In this article, a new mixing scheme based on the MLEV-16 composite pulse decoupling cycle (II) was proposed, which is less sensitive to pulse imperfections and provides net magnetization transfer over a substantial bandwidth with only limited rf power.

A two-dimensional nuclear overhauser experiment with pure absorption phase in four quadrants☆
TL;DR: In this article, a method for obtaining pure absorption phase spectra in four quadrants in a two-dimensional nuclear magnetic resonance spin exchange experiment is described, which results in a substantial increase in resolution and discrimination while maintaining a signal-to-noise ratio comparable to that of the usual magnitude spectrum.

Proton‐enhanced NMR of dilute spins in solids
TL;DR: In this article, the NMR signals of isotopically or chemically dilute nuclear spins S in solids can be enhanced by repeatedly transferring polarization from a more abundant species I of high abundance (usually protons) to which they are coupled.

Application of Fourier Transform Spectroscopy to Magnetic Resonance
Richard R. Ernst,W. A. Anderson +1 more
TL;DR: In this paper, the application of a new Fourier transform technique to magnetic resonance spectroscopy is explored, which consists of applying a sequence of short rf pulses to the sample to be investigated and Fourier-transforming the response of the system.
