Carbon-13 NMR studies of solid bisphenol-A alkanoates

Article abstract of DOI:10.1016/0022-2860(95)08902-8

Magic-angle spinning 13C spectra are reported for six bisphenol-A alkanoates, usually with cross-polarisation.These reveal effects arising from crystallographic non-equivalence, molecular motion (phenylene ring-flipping) and non-crystalline forms.The data are complemented by DSC and solution-state NMR measurements.Apparently inhomogeneous ring-flipping for some of the compounds is discussed.
