| Abstract: | By using lanthanide ions as probe of NOR to induce chemical shifts of 13C on Ln-Gly complexes, at pH=4, we can conclude that the heavy lanthanide ions are bound both to one oxygen in carboxyl and to the nitrogen in amino of glycine, but the light lanthanide ions are only bound to the oxygen. The distances of La-O in two groups are 2. 00A and 2. 40A respectively. At pH=2, all lanthanide ions are similar to the light ions at pH=2. |
