Notes

This video is one of around 310 titles, originally broadcast on Channel 7 of the ILEA closed-circuit television network, given to Wellcome Trust from the University of London Audio-Visual Centre shortly after it closed in the late 1980s. Although some of these programmes might now seem rather out-dated, they probably represent the largest and most diversified body of medical video produced in any British university at this time, and give a comprehensive and fascinating view of the state of medical and surgical research and practice in the 1970s and 1980s, thus constituting a contemporary medical-historical archive of great interest.

Contents

Segment 1 Dr Garlick introduces the topic, saying that she will explain the theory of NMR using classical physics rather than quantum mechanics wherever possible. Animated diagrams show nuclei spinning about their axes and Garlick explains their behaviour in relation to a large magnetic field applied in the vertical direction. She also discusses nuclei at thermal equilibrium; a formula is shown. She explains why different nuclei have different precessional frequencies. She uses the analogy of a motorway to explain precessional frequencies and how to measure them. Still and animated images are used as aids.

Segment 2 Garlick discusses continuous wave NMR and Fourier transform NMR. The latter method was used by biochemists. She explains this faster method of NMR and how to obtain a spectrum with it; images of molecules are used as aids in her examples. After discussing many theoretical examples she discusses a practical example of using a biological sample such as an isolated heart. End credits.
