Abstract
A cylindrical coil form, for magnetic coupling with an irradiated nuclear magnetic resonance gas sample, is provided with peripheral and longitudinal grooves. The peripheral grooves are not helical in form, but are perpendicular to the axis of the coil form to give a precisely directed longitudinal magnetic field. A first coil for providing strong magnetic coupling along the axis of the coil form is wound in the peripheral grooves, the adjacent turns being interconnected by short longitudinal sections of wire in one of the longitudinal grooves. Additional coils are provided for magnetic coupling transverse to the axis of the coil through the use of wires extending down one of the longitudinal slots and back in another longitudinal slot. The form may be of phenolic material, or may be transparent so that the nuclear magnetic resonance sample may be irradiated directly through the coil form.
