Circular dichroism of the “random” polypeptide chain
(Wiley Subscription Services, Inc., A Wiley Company, 1969-09)
The circular dichroism (CD) spectrum of an unordered polypeptide chain does not correspond, as has been assumed heretofore, to that of a charged chain such as poly- L -glutamic acid or poly- L -lysine. The latter have been ...
Influence of counterions on the helical conformations of charged polypeptide chains

Mixed crystal infrared study of chain folding in crystalline polyethylene
(John Wiley & Sons, Inc., 1969-10)
Infrared spectroscopic studies have been made of mixed crystals of linear polyethylene and perdeuteropolyethylene. On the basis of normal vibration analyses by Tasumi and Krimm it had been shown that the study of crystal ...
Influence of defects on the infrared spectra of polymers Presented in part at the Symposium on Spectroscopy of Polymers, American Chemical Society, Chicago, September 1967.
(John Wiley & Sons, Inc., 1969-01)
For an infinitely repeated regular polymer chain structure the only vibrations which are optically active are those in which the phase of the motion is the same in each unit (the factor-group modes). Frequencies for which ...
