摘要： A method for line narrowing in nuclear magnetic resonance (NMR) studies in solids is described. The method employs quasi-continuous amplitude modulation of an rf field wherein the field is eliminated at intervals for short periods of time at or about the time when the amplitude for both the maximum and minimum approach zero, these intervals creating windows where the NMR signal can be observed.

摘要： A method for adjusting the orientation of the rotation axis for a sample in a nuclear magnetic resonance (NMR) experiment includes using a field gradient in a specific direction with respect to the external magnetic field of the NMR experiment to establish a calibrated reference direction with which the rotation axis may be aligned. Preferably, the magnetic field gradient is at an angle of 54.7.degree.. A preferred embodiment of this invention includes automatic control steps in the method.

摘要： Methods and apparatus for detecting (and, if desired, imaging) the effects of magnetic resonance in a spin-containing material by measuring the magnetic force acting on a mechanical cantilever having a low damping coefficient due to modulation of the magnetic moment of the material in the polarizing field direction at a frequency substantially lower than the spin resonance frequency. Modulation of the magnetic moment in the direction of the polarizing magnetic field may be achieved by modulating (i) the magnitude of the magnetic field in the polarizing direction or (ii) the frequency or amplitude of a high-frequency magnetic field.

摘要： A method for spin imaging in solids using nuclear magnetic resonance (NMR) spectroscopy. The invention includes the steps of rotating the sample about an axis which makes a particular angle with the NMR static external magnetic field, rotating a magnetic field gradient with a spatial distribution which is related to the sample spinning axis synchronously with the sample, collecting the data while performing a solid state NMR line narrowing step, and changing the phase relation between the sample rotation and the field gradient rotation on a step-by-step basis to map out an image of the object.

摘要： This spinning apparatus for nuclear magnetic resonance (NMR) spectrometers is readily mountable and demountable in the spectrometer and is arranged for ease in loading samples to be spun. The apparatus is also arranged for ease in aligning the sample in the magnetic field for obtaining optimum results. At the same time, the apparatus is simple, and inexpensive in construction. Basically, the spinning apparatus comprises a stator assembly in the form of a nonmagnetic cylindrical body member having a conical bore arranged at an angle to the longitudinal axis of the body member lying between 45.degree. and 90.degree. and located in approximately one-half of the body member. A rotor assembly comprising a conical head portion and a cylindrical tail portion fits into the conical bore for spinning the sample which is loaded into the cylindrical portion. An elongated bore in the body member is arranged for supplying gas to a manifold arranged in the body member for application through jets into the conical bore and against the conical portion of the rotor assembly. The rotor assembly rides on a gas bearing for efficient, wear free and less critical operation and preferably has fluting for better drive. The conical head portion preferably is cut with a compound angle for easier starting and for importing greater stability in spinning.
