From the position of the resolved absorption and CD bands of helical and
randomly coiled polypeptides ( see Section IV ) it is apparent that ay and az at d =
193 nm and 12 = 225 nm are not actual rotatory strengths but empirical
parameters ...

of the far - UV CD of this polymer only if it existed in the right - handed a - helical
conformation ( see also Chapter 23 , this volume , Section II , G , 2 ) . Thus , the
233 nm trough characteristic of the right - handed a - helix has shifted to 238 nm .
