## Abstract The topological resonance energy (TRE) model was introduced independently by the Zagreb Group (in 1975) and by Aihara (in 1976). Several practical obstacles arise in the computation of TRE. Ways to surmount them are pointed out. Descriptions of algorithms, optimizations, and the efficie

β¦ Synopsis
NonempirIcal HF SCF MO ~lculauons have been performed for the topologicilly related o-and p-benzoqumones. The SCF n-h10 eigenvalues obtamed using srandard geometnes are m mmplete agreement with the topologuleffedon-molecular*,rbitals (TEMO) theorem; the same ergenvalue spectra computed wrth optirruzed geometnes exhibit threr energy mterals where the sequences of n-MO ergenvalues m=rt their order. A detailed analysis of the perturbations on the TEMO pattern yla the perturbational-varia.tlonal Rayleigh-Rirz procedure has rewzaled the physical ongin of these mversons * This is Part VI in a senes in which ref.

Binding energies and stabilities of Na + with bidentate ethylene diamine were studied using ab initio MO calculations with a 6-31G\* basis set. The computed results for bidentate ethylene diamine were compared with those for two (monodentate) CH3NH 2 molecules.
