Life
Work
Protons and neutrons in the atomic nucleus behave like
small spinning magnets. Accordingly, atoms and molecules assume a certain orientation in a magnetic field. This can be dislodged, however, by radio waves of certain frequencies that are characteristic for different atoms. Known as resonance frequencies, these are also affected by the atoms' chemical surroundings. As a result, the phenomenon can be utilized to determine the composition and structure of various molecules. To accomplish this, Richard Ernst developed
highly sensitive and high resolution methods in the 1960s and 1970s.
