Abstract

Thumbnail image of graphical abstract

A new acquisition: Based on “phase-shifted mirrored sampling” (PMS) of indirect evolution periods of multi-dimensional experiments, new acquisition schemes eliminate, without application of a phase correction, dispersive signal components that exacerbate peak identification and shift peak maxima. The resulting enhanced resolution is of particular value for systems with high chemical shift degeneracy.
