Preferred Label : Z-value;
IUPAC definition : An index of the ionizing power of a solvent based on the frequency of the longest
wavelength electronic absorption maximum of 1-ethyl-4-methoxycarbonylpyridinium iodide
in the solvent. The i Z /i -value is defined by: \[Z \frac{2.859\,\times\,10 {4}}{\lambda}\]
where Z is in kcal mol-1 and λ is in nm.;
Origin ID : Z06737;
