An NMR sample tube is offered which can be spun at high speed stably. The NMR sample tube is adapted for use in solid-state NMR spectroscopy and includes a tubular member, spacers, and cover bodies. The spacers are disposed inside the tubular member. Each spacer has first and second surfaces located on opposite sides. The first surfaces of the spacers define a space filled up with a sample. The tubular member has openings which are closed off by the cover bodies.

A method of NMR measurement which achieves background suppression based on a technique employing differences in RF magnetic field strength while alleviating the problem that less latitude is allowed in setting the number of signal accumulations. This method suppresses a background-derived signal emanating from the material of an NMR probe. The method starts with applying an RF pulse sequence consisting of a 90 pulse and subsequent one or more 180 pulses to a sample to induce an NMR signal and detecting the signal. This application is repeated while varying the RF phases of the pulses to induce NMR signals in accordance with a cogwheel phase-cycling scheme to induce NMR signals. The NMR signals are detected. The detected NMR signals are accumulated.
