A capacitively shortened coaxial resonator for making nuclear magnetic resonance measurements includes inner and outer concentrically arranged metal cylinders (12, 14). The cylinders define therebetween a sample region (15) and are shorted electrically by a conductive cap (18) which closes one end of the inner and outer cylinders (12, 14). A capacitor (16) is connected across the cylinders at the opposite open end and functions to resonate with the inductance of a coaxial conductor formed by the short circuited cylinders. Samples in a container (20) placed in the sample region (15) are mounted on an air bearing (24, 28) and rotated by means of air holes (28).
