Variable-temperature 13C CP/MAS NMR experiments were carried out on crystalline (±)-3,4-di-O-acetyl-1,2,5,6-tetra-O-benzyl-myo-inositol. Three distinct phases can be distinguished from their NMR characteristics, each stable over a well defined tempe

Resonances from two distinct thiazolidine ring conformers have been resolved in the 13C CP-MAS spectra of frozen aqueous solutions of penicillins; the relative intensities of the resonances correlate well with previous estimates of the populations of
