## Abstract NMR measurements of anisotropic diffusion were studied using a three‐dimensional random‐walk model. It was found that the apparent diffusion coefficient can be expressed in a canonical form as the product of a diagonal matrix, an orthonormal rotation matrix, and a vector representing th
