NMR INSTRUMENTATION SINCE VARIAN A-60

The introduction of the Varian A-60 NMR spectrometer in 1961 made possible the routine utilization of this tremendously important technique in many laboratories. At that time there were, however, a number of difficulties with both the A-60 and the NMR technique itself. The major instrumental developments which have been made in an effort to solve these problems are discussed in this review. A tabulation of the characteristics of the presently available commercial instruments is given.
