31P and 13C NMR of Transition Metal Phosphine Complexes

The book delves into the evolution of nuclear magnetic resonance (NMR) technology, highlighting its initial focus on proton measurements and the challenges faced in studying less common nuclei like carbon, nitrogen, phosphorus, and fluorine. It discusses the technical hurdles, such as low natural abundance and spin-spin coupling, that complicated these studies. Significant advancements, particularly the introduction of broad band 1H-decoupling and Fourier Transform methods, are presented as pivotal breakthroughs that improved signal clarity and enabled the exploration of complex metal catalysts.
