A method for rotating-frame NMR diffusometry in the fringe-fieldB1gradients of solenoid RF coils in standard probeheads is described. A 5 mm RF solenoid coil, for instance, producesB1gradients of up to 3.3 T/m. The gradients can be enhanced by so-called flux concentrators so that values comparable to those common in laboratory-frame PGSE experiments should be feasible. The principle of the technique is to produce azmagnetization grid with the aid of aB1gradient pulse. The wavenumber of the grid is varied by the length of the preparation pulse. After a certain diffusion delay, the grid is rendered as an image using a rapid rotating-frame-imaging technique. TheB1gradient need not be constant. Diffusion coefficients are rather evaluated locally based on the localB1gradients. Single-transient diffusion experiments in toroid resonators, and the employment of theB1gradients produced by the skin effect of conducting materials are suggested.
