Abstract
The problems of pseudo-symmetry are often appeared in the crystal structure. This paper discusses some possible kinds of pseudo-symmetry in molecule and between molecules. The unknown polypeptide crystal ctructure (M. W. =1111.4) have been solved success fully by using the pseudo-symmetry idea.
