✦ Synopsis

Abstract

A detailed assignment of the ^13^C chemical shifts of κ‐ and ι‐carrageenans in their Na^+^ and K^+^ forms in D~2~O and dimethylsulfoxide is given. Evidence of the conformational transition induced by temperature variation in the absence of any gel formation on κ‐carrageenans is also presented. This evidence is based on ^13^C‐nmr and optical rotation experiments.
