A newly developed acyl halide molecular mechanics MM3 force field can accurately calculate molecular geometry, usually to within experimental error. The new force field can also calculate vibrational frequencies. The acyl halides studied were formyl halides, acetyl halides, propionyl halides, n-buty

β¦ Synopsis
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, propionyl halides, n-butyryl halides, 2-methylpropionyl halides, Γ₯nd 2,2-dimethylpropionyl halides. The rms deviations were 0.005 A and 1.06Π for bond lengths and bond angles, respectively. MM3 was in good overall agreement with the available structural,

## Abstract The conformations of the 16βmembered macrolide antibiotic leucomycinβV (**1**) were studied with molecular mechanics. LeucomycinβV contains a conjugated Οβelectron fragment and necessitates special treatment with the MM3(Ο) modeling protocol. Comparison was made with results from the st
