✦ Synopsis

The ion-exchange transition of Na-DNA -D H-DNA in concentrated salt-free solutions is accompanied by strong variations in CD spectra. The rotational force of the negative band I h,, I decreases when going to H-DNA by about 4 times, and the value of Ar,,, by 1.2 times. These changes are irreversible to a considerable extent, which is evident because the spectra of Na-DNA obtained by neutralizing iaoionic H-DNA solutions with NaOH or by the ion-exchange method significantly differ from those of Na-DNA taken by dissolving solid Na-DNA in deionized water. It has been ahown that additions of NaCl to an bionic solution of DNA leads to variations of spectra, typical for deprotonation processes as well as for an increase in DNA hydration.

Solid-state CD spectroscopy can provide valuable information on conformation, intermolecular interactions, including chirality induction, and enantioselective reactions which occur specifically in the solid state. The technique can, however, suffer from serious artifacts. Some examples of solid-stat

## Abstract The CD. spectra of carotenoids in the 220‐500 nm region may by inspection be classified as (a) essentially __Conservative__, (b) __intermediate__, or (c) essentially __nonconservative__. A conservative spectrum shows in that spectral region a sequence of 5‐6 relatively sharp __Cotton__
