ABSTRACT
Because of the quantum mechanical time scale of the NMR instrument, one can study certain time-dependent phenomena that are not generally . accessible to the other branches of spectroscopy. Both molecular motion and chemical exchange may affect the appearance of NMR spectra. This unique characteristic has important implications in the study of Grignard reagents. This chapter is designed to provide information to the chemist who uses NMR as an investigative tool. It is assumed that the reader has a basic understanding of the theory and practice of NMR spectroscopy. Those who do not may find it helpful to consult one of several excellent texts on NMR spectroscopy [ 1-1 3].
