Chapter 4 - One-Dimensional Techniques

Abstract

This chapter introduces the most common 1D NMR techniques used in the chemical laboratory. It initially considers the simplest single-pulse excitation method and describes how this should be executed to obtain optimum sensitivity or accurate quantification of samples. It then introduces the concept of spin decoupling and describes its application for homonuclear and heteronuclear decoupling. The use of spin-echoes for spectrum editing is described followed by consideration of methods that also employ polarisation transfer with spectrum editing for enhanced performance. The final section describes techniques that are specifically tailored to the observation of rapidly relaxing quadrupolar nuclei.
