Rotary dispersions of 17 kinds of refined amino acids of known purity derived from natural_ proteins have been determined and its application. to analytical chemistry has been investigated. (1) The value, [M] =A/(λ2-λc2) -B/λ2, of simplified Drude equation of each amino acid was sought and it was compared with the curve prepared from experimental results. (2) Graphical representations of λ2-1/ [M] were prepared and the results showed straight lines in all cases, except for tyrosine. By utilization of this finding, it was suggested that the test on purity of amino acids was possible. (3) Ultraviolet absorption spectra of amino acids have been estimated and the relation between the wave length of the maximum λmax, and λc (specific vibration wave length) obtained from rotary dispersion in Drude equation has been investigated.
