title: Charge-transfer interactions between metal ions and some uracil derivatives.
abstract: The interaction between Cu2+ and a few uracil derivatives has been investigated by means of electron spin resonance and optical absorption studies. It could be shown that a charge transfer interaction occurs. Its strength depends upon the electron attracting or releasing properties of the substitutents of the nucleobase.
