Title: Quantitative Determination of Wax Contamination in Polystyrene HIPE Foam Using Solid-State NMR

Abstract

Differences in molecular mobility between polystyrene foam and Brij-78 wax results in vast differences in the 1H nuclear magnetic resonance (NMR) linewidth. This allows for the convenient determination of wax content in the polystyrene foam components of inertial confinement fusion targets via solid-state NMR. Lastly, contamination levels as low as 0.1% are easily recognized and quantified, and the detection limit is calculated to be 0.02% even when only 32 transients are recorded.

  • A multi-spectrum technique for facile, quantitativedetermination of lead in solid materials using solid-state 207Pb NMR thatavoids the major problem of uniform excitation across a wide spectralrange has been demonstrated. The method can be employed without chemicalseparation or other chemical manipulations and without any prior samplepreparation, resulting in a non-destructive analysis, and producingresults that are in agreement with gravimetric analyses of mixed samplesof the lead halides.
  • The matrix effects on the high-resolution solid-state NMR line shapes of bistable molecules that are subject to rapid exchange between two isomers is described. Matrix effects are modeled in terms of a static superposition of different molecular environments or sites characterized by different equilibrium constants, i.e., differently perturbed double minimum potentials of the isomerism. A theory of inhomogeneously broadened NMR line shapes based on this model is presented. In addition, the effects of exchange between the different sites on the NMR line shapes are treated. Site exchange induces homogeneous line broadening and eventually liquid-type NMR spectra, where all molecules experiencemore » a similar motionally averaged effective double minimum potential of the isomerism within the NMR time scale. As an example, the variable-temperature /sup 15/N CPMAS NMR spectra of a /sup 15/N-enriched tetraaza(14)annulene dye (TTAA = 1,8-dihydro-5,7,12,14-tetramethyldibenzo(b,i)(/sup 15/N/sub 4/)-(1,4,8,11)-tetraazacyclotetradeca-4,6,11,13-tetraene, tetramethyldibenzotetraaza(14)annulene, C/sub 22/H/sub 24//sup 15/N/sub 4/), in the crystalline state and dissolved in glassy polystyrene, are presented. The /sup 15/N enrichment of TTAA is described, including the synthesis of its precursor o-phenylenediamine-/sup 15/N/sub 2/. Solid-solution NMR studies provide information about details of molecular rearrangements in a time scale of slow solvent reorientation. In addition, dyes such as tetraaza(14)annulenes can be useful for probing microscopic order and motion in glasses by NMR. 52 references, 8 figures.« less
  • The quadrupolar and chemical shift tensors, as well as the relative orientation of the two principle axis systems, are accurately determined using a two-dimensional nuclear magnetic resonance technique. Good agreement between experimental and simulated two-dimensional spectra is obtained for a series of rubidium and sodium compounds at multiple magnetic field strengths. Extension of this technique to correlate the quadrupolar and dipolar interactions, as well as the incorporation of a purely isotropic dimension resulting in a three-dimensional experiment is also discussed. {copyright} {ital 1996 American Institute of Physics.}

  • Here, we report that spatial (<1 nm) proximity between different molecules in solid bulk materials and, for the first time, different moieties on the surface of a catalyst, can be established without isotope enrichment by means of homonuclear CHHC solid-state nuclear magnetic resonance experiment. This 13C– 13C correlation measurement, which hitherto was not possible for natural-abundance solids, was enabled by the use of dynamic nuclear polarization. Importantly, it allows the study of long-range correlations in a variety of materials with high resolution.
