Two-dimensional spectroscopy. Application to nuclear magnetic resonance

TLDR

The paper discusses the possibilities for extending spectroscopy to two dimensions. It develops the basic theory of two‑dimensional spectroscopy, describes its application to nuclear magnetic resonance, and outlines numerous applications such as energy‑level diagram elucidation, multiple‑quantum transition observation, and high‑resolution spectra recording in inhomogeneous magnetic fields. The study demonstrates several of these applications and presents experimental results for simple spin systems.

Abstract

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.
