Pulsed and Fourier Transform NMR Spectroscopy
Modern Fourier transform (FT) NMR spectrometers have been available commercially for only about six years, but in this short period of time many advances and improvements in instrumentation have been made. The first FT-NMR instruments were conventional, continuous wave (CW) spectrometers to which a pulsed RF transmitter, a modified receiver-detector system, a signal-averaging device, and a small minicomputer were attached. It is not too surprising that all of the early FT instruments were quite expensive ($100,000 to $200,000), difficult to operate, fraught with numerous operating problems, and not very reliable.
