The principal values of the chemical shift tensors of all 13 C and 15 N sites in two antibiotics, ampicillin and penicillin-V, were determined by 2-dimensional phase adjusted spinning sideband (2D-PASS) and conventional CP/MAS experiments. The 13 C and 15 N chemical shift anisotropies (CSA), and the
## Abstract The twoโdimensional QUADSHIFT experiment is introduced, which permits the separation of chemical shifts and quadrupolar couplings in solidโstate magic angle spinning NMR spectra of powder samples. The technique was applied to partially deuteriated norcamphor and camphor under slow magic
