  • Method and apparatus for high resolution nuclear magnetic resonance spectroscopy
    Patent number: 4305036
    Abstract: A nuclear magnetic resonance line broadened by an inhomogeneous magnetic field can be narrowed by rotating the sample. This, however, produces rotational side bands having a frequency equal to the frequency of a main signal plus/minus integer multiples of the speed of rotation. The generation of such spurious rotational side bands is avoided by varying the speed of rotation of the sample within a predetermined range of speeds. The lower limit of said range should be high enough to provide for narrowing the nuclear magnetic resonance lines by rotating the sample.
