## Abstract Two possible conformations for poly(__cis__β5βethylβDβproline) have been identified and characterized by using combinations of ^1^Hβ and ^13^CβNMR, CD, and ORD spectroscopic techniques. Both forms have helical conformations similar to those of poly(Lβproline) characterized by different

## Abstract By means of carbonβ13 nmr (at 25 MHz) the __trans/cis__ conformer ratio in glycylβLβproline has been measured in aqueous (D~2~O) solution over the temperature range 33β96Β°C. It is found that Ξ__H__^0^ = β4.2 kJ/mole and Ξ__S__^0^ = β9.7 J/mole/K. Measurements of the __T__~1~ values for
On page 1763 of this article, the title for Table I1 was erroneously given as,."Assignment of the Spectra in the Region from 800 to 700 cm-' of &Form Poly(L-valine)". The title should read, "Assignment of the Spectra in the Region from 800 to 200 cm-' of &Form Poly( L-valine)".
