Abstract

original image

A piece of cake: Slice-selective excitation (SSE) of nuclear spins provides spatially resolved NMR spectra that can be used to follow the unidirectional swelling of cross-linked polystyrene. In addition to concentration profiles for the solvent and solute, the method yields 2H and 7Li quadrupolar splitting profiles that can be used to assess and improve the sample homogeneity for anisotropic NMR measurements.
