Pulse Fourier Transform ¹³C‐NMR Spectroscopy, Principles and Applications

Abstract

Abstract As a result of the development of pulse Fourier transform NMR spectroscopy 13 C resonance has become accepted as a means of elucidating the structures of organic compounds having the natural 13 C abundance. Assignment of the signals is facilitated by broad‐band and off resonance proton decoupling and by knowledge of longitudinal relaxation times. The pulse Fourier technique, which is more sensitive and faster than conventional NMR spectroscopy because of multi‐channel excitation, allows 13 C measurements within a short time even on dilute samples of high molecular weight compounds without prior enrichment in 13 C.
