Abstract
- 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 the different conformers in liquid aqueous solutions.
