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.

Key words: Amides, 14N relaxation, Solvent isotope effects
