摘要：

Precise complex permittivity spectra of the amides formamide, N-methylformamide, N,N-dimethylformamide, and N,N-dimethylacetamide and of the dipolar aprotic solvents acetonitrile, propylene carbonate, and dimethylsulfoxide were determined in the frequency range 0.95-89 GHz. The dielectric relaxation of all liquids is non-exponential, ranging from a small symmetrical relaxation time distribution for acetonitrile to three discrete dispersion steps for NMF. © 1990.
