✦ Synopsis

In marked contrast to the most favourable folded conformation, predicted from ab initio quantum mechanical calculations, the crystal structure analysis of the model system incorporating -CONH-CH2-CH2-CONH-moiety, revealed the existence of an all-ant~" conformation, characterized by the backbone torsion angles: ~ *~ -146", ~t ~ 172" and ~¢ ~ 155". Potential applications of the residue to form highly ordered, novel 13-~eet like structure(s) with distinct faces have been suggested.

## Abstract The postulate of geometric equivalence of the monomeric units of a tactic chain with regard to an axis (I) and the postulate that the conformation is such that the internal energy of the chain, considered as not subjected to external forces, is the lowest (II), can be applied to the pre

## Abstract Summary: The vast majority of head‐to‐tail stereoregular crystallizable polymers with an isotactic structure generally assume a helical symmetry in the crystalline state, compatible with the regular repetition along the chain axis of isomorphous isoclined units. There are at least two c
