Substitution at the 7, 9, and 10-Positions

Dewar uses these differences as a way of approximating localization energies. In other words, instead of calculating the ir—electron energy of naphthalene by the RS procedure, it is used to estimate the energy of the localized intermediates that corresponds to substitution at the 1 and 2 positions. The outcome is as follows (omitting the appropriate multiples of...
