Ion-pairs of 2-benzoylbenzoic acid-chiral amine display a large induced circular dichroism ( ICD ) on the n -h" transition of the carbonyl group under lower concentration of the salt than 10s2 mole/l in non-polar solvents such as 1 carbon tetrachloride and benzene. The origin of the large ICD effec

The chiroptical properties of phospholipids were investigated by optical rotatory dispersion and circular dichroism. The spectra of phosphatidylcholine varied with the solvent used. The sign of the circular dichroism effects differed in some cases from previously reported. The results show that it i
Optically active amines Am\* induce relatively strong Cotton effects within the d +d bands in their unidentate neutral complexes of the type [CuIm,-Am:] (CuImz = Copper imidate as e.g. CuSuz, Su = succinimidate).

It is known that rigid short range structures such as certain model amides' and diketopiperazinesz can produce ORD and CD spectra with Cotton effects somewhat similar to those displayed by stereo-ordered macromolecules. In this connection, unsaturated peptides,3 in which the rigidity of the chain is
