Several theoretical techniques for calculating the dielectric constant of the solution from these two parameters are discussed together with the relative merits of each method. The results obtained for glycine, diglycine, alanine and urea, none of which had been previously measured at these frequencies, are compared with the extrapolated values from previous work in the microwave region.
