ABSTRACT
Let me take you back to around 1960, the early days of nuclear
magnetic resonance (NMR) spectroscopy; some of you younger
readers may think it was medieval times, but it was quite not that
bad! At that time, there were essentially only two NMR instruments
in entire Sweden: one at the Physics Department at the Uppsala
University and one at the Royal Institute of Technology in Stockholm.
This was, of course, in the pre-superconducting era, and at the core
of these two Varian spectrometers were large heavy electromagnets
with a field strength of 0.9 T (Uppsala) and 1.4 T (Stockholm) (40
resp. 60 MHz 1-H NMR frequency).
