A number of imldaeoles and epoxides, important for the study of the mechanisms of epoxy resin cure, have been tritiated by one-step catalytic procedures. Tritium nuclear magnetic resonance spectroscopy has been employed to determine the positions and extent of labeling in these compounds and the obs

Samples of di-, tetra-and octapropylene glycols which are uniform in chain length have been prepared and studied by ~3C NMR spectroscopy, with CH and CH 2 subspectra obtained by the DEPT technique. A pure sample of the head-to-head isomer of dipropylene glycol was prepared, but other samples were mi
As clinical applications of MRS grow in number and complexity, there is a need for standardized methods for characterizing the performance of volume selection techniques. The results are presented of a thorough evaluation of a particular implementation of ISIS performed using a procedure which forms
Several procedures for synthesis of stereoregular poly(methacrylic acid) have been examined and the polymer characterized by (I~C)NMR. Using d 6 DMSO as solvent for spectroscopy gives better spectra than those previously obtained using aqueous solutions and stereoehemical splittings can be resolved
Two-dimensional homo-and heteronuclear NMR chemical shift correlation techniques were applied in the characterization of five tricyclic polychlorinated C 10 hydrocarbons, chlordene (1), heptachlor (2), trans-nonachlor (3), ห-chlordene (4) and -chlordene (5), which are spread globally in the environm
