Abstract

CD. curves have been recorded for α‐aryl‐α‐amino acids, esters and amides related to α‐phenylglycine, α‐phenyl‐alanine and their N‐dimethyl derivatives, and for the corresponding α‐cyclohexyl‐α‐amino acids and esters. Compounds with the (S)‐configuration at the single asymmetric carbon atom give strong positive Cotton effects near 220 nm. The conformations of the acids are discussed and compared with those of other α‐amino acids.

## Abstract Optical rotatory dispersion (ORD) and circular dichroism (CD) spectra of single‐ and multistranded polyribonucleotides undergo extensive changes on binding of the silver ion. These changes are consistent with the proposition that Ag(I) binds to the heterocyclic bases and not to the phos

An analysis of optical rotatory dispersion and circular dichroisin of RNA is described which leads to an estimate of the degree of base pairing. By the use of new standards for the double-helical parts of the molecule, based on data for two-stranded viral RNA species, a good fit between calculated a
