Part One: Extensions of the E and C Equation. Part Two: Measurements of Dielectric Relaxation in Strontium Doped Lanthanum Orthoferrites Using Dielectric Time Domain Spectroscopy

Part One. The relationships between the Kamlet-Taft β-π\sp\* solvation approach and the E and C equation are investigated. The breakup of solvation effects into nonspecific (π\sp\*) and specific Lewis base interactions (β) is found to be consistent with the E and C approach. The β parameter is shown to be a special case of the E and C equation for acids with a C$\sb{\rm A}$/E$\sb{\rm A}$ ratio of 0.03. In addition, the nature of "family dependent" linear free energy relationships is discussed in E and C terms, showing that the two term E and C approach predicts the existence of these relationships and can correlate them without breaking the data into donor types.
