Abstract

Temperature‐dependent conformational transitions of spin‐labeled poly(U) at low temperature in spermidine and cesium chloride buffer have been measured by electron spin resonance spectroscopy. The Arrhenius plot shows the existence of the order‐disorder transition at a temperature close to that obtained from absorbance temperature profiles. However, in addition the formation of an intermediate state is observed during the melting of the ordered poly(U) to its random coil.

In egg lecithin-water lamellar phases, spin-labeled stearic acid gives two superimposed ESR spectra which are only well resolved when the temperature is greater than 30 degrees C. These two spectral components are attributed to the dissociated and non-dissociated forms of the fatty acid carboxylic g

## Abstract p‐Toluic acid‐ring‐^14^C was synthesized by the Friedel‐Crafts p‐carbamylation of toluene‐ring‐^14^C with N,N‐disubstituted carbamyl chloride and subsequent hydrolysis. The radiochemical yield was 61%. An attempt was made to apply this method for the synthesis of benzoic acid‐ring‐^14^C
