WebThe correspondence between method A and the simple Huckel method can now be demonstrated by showing the one-to-one relation between Huckel 12, values obtained empirically and the h, calculated by [32] from the valence-state energy data. The only difficulty in such an analysis is the choice of appropriate Huckel h, to be used.
