Application of triple-channel 13C{1H,19F} NMR techniques to probe structural properties of disordered solids

Abstract

Triple-channel ¹³C MAS NMR experiments are carried out to characterize intermolecular interactions in disordered molecular solids containing fluorinated n-alkanes; an approach involving a combination of ¹H→¹³C and ¹⁹F→¹³C cross-polarization experiments, with both single-channel (¹H) and double-channel (¹H,¹⁹F) decoupling is developed to assign resonances for a given type of ¹³C nucleus in different intermolecular environments.
