✦ Synopsis
A force field has been developed, on the basis of available experimental and partial retention of diatomic differential overlap (PRDDO) data, to permit molecular mechanics calculations on azoxyalkanes. The calculated structures and enthalpies of formation are in fair agreement with experimental results. The calculated enthalpies of formation and strain energies are compared with the corresponding quantities for analogous azoalkanes.

Group equivalents which are useful for converting energies derived from ab initio calculations into enthalpies of formation have been obtained. They allow AHf to be estimated from 6-31G\* energies with an uncertainty on the order of k 2 kcal/mol.
The MM4 force field has been extended to the title class of compounds. The vibrational spectra, structures, conformational equilibria, and heats of formation have been studied for 47 conformers of 29 compounds. In general, the properties may be calculated with accuracy that is competitive with that
A new molecular mechanics MM3 force field has been developed based on various experimental data as well as ab initio calculations. Computergenerated molecular structures and energy values were compared with experimentally determined data. The acyl halides studied were formyl halides, acetyl halides,
