摘要: Abstract The circular dichroic absorption spectra of the phenol and indole chromophores have been determined in near ultraviolet water, dioxane, dimethyl sulfoxide with diketopiperazines tyrosine tryptophan. molecular ellipticities are several times as large those equivalent linear dipeptide forms. enhancement optical activity appears to reside rigid conformation aromatic diketopiperazines.
