✦ Synopsis

Variable

-temperature solid-state 13C NMR measurements show effects due to molecular motion in spectra of 2,2-bis[p-(2,3-dihydroxypropoxy)phenyl]propane (BADGETOL), which is a derivative of bisphenol-A diglycidyl ether. Features in the spectra indicate that the motions present may not be characterized by a simple exponentially decaying autocorrelation function (single correlation-time process), and a study of the coalescence of doublets due to reorientation between non-equivalent sites strongly suggests that the motions are more properly characterized by a spatially inhomogeneous distribution of single correlation-time processes.
