## Abstract The conformational transition of polyβLβtyrosine in 0.1__M__ KCl was investigated by ORD and infrared spectroscopy, potentiometric titration, and sedimentation velocity experiments. It is shown that the fully ordered conformer is obtained by slow titration of the random coil with 0.1__N
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
