| Abstract: |
| Based on the theories of heteronuclear single quantum coherence(HSQC) and heteronuclear multiple-quantum coherence(HMQC),1D-nonselective-1H-31P HSQC,heteronuclear single quantum coherence and multiple-bond correlation(HSQMBC)were applied and 1D nonselective 1H-31P HMQC pulse sequences were designed for screening the organophosphorous(OP) compounds.The differences among these methods were studied,especially in peak shape and sensitivity.From results of the analysis on the OP compounds in the OPCW proficiency test,1D nonselective HMQC method has been proved to be the most effective and sensitive in NMR experiments so far. |
