| 摘 要： | 利用化学位移、弛豫时间、自扩散系数、NOE效应等多种核磁共振(NMR)信息对芥子气(HD)与阴离子表面活性剂十二烷基硫酸钠(SDS)的作用机理进行了研究.加入HD后,化学位移的变化表明HD主要增溶在SDS胶束的H4,H3及H5区域,其水解产物更靠近H5区域;H4和H5的自旋-自旋弛豫时间(T2)与自旋一晶格弛豫时间(T...

| Abstract: | The interaction between mustard gas(HD) and sodium dodecylsulfate(SDS) was analyzed by NMR information,e.g.chemical shift,diffusion,relaxation and the nuclear overhauser effect(NOE).The chemical shift results indicated that HD was located around H4,H3 and H5 of SDS,and the hydrolysates of HD were near with H5.The ratios of spin-spin relaxation(T2) to spin-lattice relaxation(T1) of H4 and H5 increased after adding HD,indicating that the SDS micelle became loose and the hydrolysates of HD were located around ... |
