摘要:
It is now well known that zinc is crucial for the synthesis of nucleic acids and, consequently, for cellular division. However, Zn-67, the NMR-detectable isotope, is one of the isotopes most poorly studied by NMR. The strategy used for NMR studies is the substitution of Zn by Cd-113. In this work, we employed C-13, Cd-113 NMR (CPMAS), X-ray and DFT calculation in order to evaluate the Zn-Cd substitution using 8-hydroxyquinoline like prototype compound. Our results show that there are strong structural and electronics effects are involved in the substitution. (C) 2008 Elsevier B.V. All rights reserved.
