• The CD and ORD of D-phenylglycine and L-phenylalanine were measured at various pH's. The superficial small pH dependence of the CD maximum around 220 mμ and the anomalous large [θ] value at the CD maximum in both aromatic amino acids suggest an interaction between the <SUP>1</SUP><I>L<SUB>a</SUB></I> transition of the benzene ring and the <I>n</I>→π<SUP>*</SUP> transition of the carboxyl group. The ORD and CD of L-α-amino-β-benzalpropionic acid, L-α-amino-β-benzylpropionic acid, and L-2-amino-4-phenyl-butanol-1 were also measured, and the screening effect of the methylene groups which exist between a benzene ring and an asymmetric carbon atom was discussed.
