Thermal and charge induced random coil to a-helii transitions of poly-cglutamic acid (PGA) were measured by optical rotatory dispersion in various solvents. The data of PGA in 0.1M NaCl were analyzed by the Zimm-Rice theory. Enthalpy and entropy changes for the coil-to-helix transition in the unioni
## Abstract A polarimetric electric‐field‐jump relaxation apparatus is described and used to determine the relaxation spectrum for the helix–coil transition of poly(α,L‐glutamic acid) in water at 24°C. A maximum relaxation time of 1.7 μc occurs at the transition midpoint (pH = 5.9) yielding a rate
The anisotropic rotational motion of the backbone and the side chains of poly(t glutamic acid) in the a-helical structure was investigated using the ' G T , and T2 relaxation times of all carbon atoms with directly attached protons, obtained at a I T -Larmor frequency of 67.89 MHz. The evaluation of
