18. Specifically, this refers to the phase of the I+ density matrix element, or, equivalently, the signal phase as detected on a typical spectrometer.

27. More correctly, they generate corrective phases at a much slower rate than hardware matching pulses.

30. Generally, when we refer to "position" or r, we refer to the coordinate(s) along which the applied gradients vary.
31. Note that all terms not containing are the same for both adiabatic full passages and will cancel.
32. 2 is the effective decay constant for the FID envelope. Note that when considering diffusion in the presence of a gradient, this relation becomes somewhat more complicated, as detailed in the Appendix.

35. - 22 rad+π rad for two π /2 pulses.
36. Although we expect larger matching corrections to be achievable and useful in single-sided systems than in the typical spectrometer system demonstrated here, we note that this would only further obscure the (blue) partially corrected spectrum, rather than affecting the (red) fully corrected spectrum.
