| 摘 要： | 本文测定了己内酰胺7水(重水).二甲基乙酰胺/水(重水)和丙烯酰胺7/水(重水)体系中N-14在低浓度区域的弛豫时间,考察了四极弛豫的溶剂同位素效应,虽然所研究的酰胺分子大小不一,但在无限稀释的溶液中,仍然可以表明这些酰胺分子的运动完全受溶剂分子的控制。

| Abstract: | N-14 relaxation times of some amides(caprolactam,N,N-dimethy lacetamide,acrylamlde) in water or deuterated water solutions were measured by inversion-recovery technique. The solvent isotope effects on nuclear quadrupolar relaxation times were discussed. The rcsults show that under infinite dilutions, the kinetica of these solute moleculcs are still controlled by the solvent molecules although they have different molecular weights. |
