A simple model for deuterium cross-polarization magic-angle spinning nuclear magnetic resonance at the interphases of amorphous materials.
The structure and composition of the interphase at the boundary of two immiscible phases has long been the subject of experimental and theoretical studies in polymer science. Cross-polarization between protons and deuterons offers the potential for elucidating the composition of the interphase if one of the immiscible phases is deuterated. A prerequisite for such an analysis is the establishment of an experimental protocol for reliable spin counting in 1H-2H cross-polarization magic-angle spinning (CP-MAS) spectroscopy. In this paper we present a simple model for the quantitative analysis of deuterium CP-MAS spectra. The model will be applied to the characterization of the polystyrene-b-poly(methyl methacrylate) interphase in a subsequent publication.
