Single crystals of POAHP I1 were grown from acetic anhydride, a solvent in which POAHP I is thought to be stable. The single crystals gave an electron diffraction pattern whichospecified a hexagonal unit cell and the lateral spacing between molecular chains (11.4 A). There is reasonable indication t

Poly-0-acetyl-hydroxy-L-proline, forms I and I1 have been studied by optical rotatory dispersion (ORD) and ultraviolet spectrophotometry in solution and in the solid state. Cotton effects of opposite sign, but not mirror images, were observed in the 250 mp region for the two forms (Form I, peak 278
