Conformational dissymmetry. Circular dichroism of amino acid and peptide complexes

A number of Pd(II) and Pt(II) complexes of amino acids and dipeptides have been isolated and characterized. The solution and solid-state circular dichroism of the amino acid complexes show a fairly consistent pattern, which is opposite to that shown by the dipeptide complexes. Some of the problems associated with the interpretation of the spectra in terms of spectroscopic assignment and structural features are discussed.
