DETECTION OF TRACE AMOUNTS OF CHEMICAL WARFARE AGENTS AND RELATED-COMPOUNDS IN RUBBER, PAINT, AND SOIL SAMPLES BY H-1 AND P-31(H-1) NMR-SPECTROSCOPY

H-1 and P-31{H-1} NMR spectroscopy was used in the identification of c hemical warfare agents and related compounds present in trace amounts in rubber, paint, and soil samples, The work was done as part of an in ternational Trial Proficiency Test of laboratory performance, NMR spec troscopy provided identifications of bis(2-chloroethyl) sulfide (musta rd), bis(2-chloroethylthio)ethane (sesquimustard), dibenz[b,f][1,4]oxa zepine (CR), bis(2-hydroxyethyl) sulfide (thiodiglycol), and cyclohexy l ethylphosphonate, and the presence of cyclohexyl methyl ethylphospho nate, 2-methoxyethyl pinacolyl methylphosphonate, and ethylphosphonic acid was supported, One of the spiking compounds, dithiane 1,4-cyclohe xane-1-oxide, was not detected, This report describes sample preparati ons, experiments, spectral analyses, and the results obtained by NMR s pectroscopy.
