Magnetic relaxation dispersion probe.
The magnetic field dependence of nuclear spin-lattice relaxation rates provides a powerful approach to characterizing intra and intermolecular dynamics. NMR spectrometers that provide extensive magnetic relaxation dispersion profiles may switch magnetic field strengths rapidly by either moving the sample or by changing the current in an electromagnet. If the sample is moved, the polarization and detection fields may be very high, which provides both high sensitivity and resolution. This report summarizes the design of a pneumatic sample transport system for glass sample containers that may be used in either a dual magnet spectrometer or in a single magnet system that exploits the fringe field as the secondary magnetic field.
