Abstract
The infrared and Raman spectra of [bis(glycylglycinato)calcium chloride]n and its isotopic complexes containing metal and hydrogen isotopes have been measured. A large isotope shift of more than 4 cm-1 on 40Ca and 44Ca substitution has been observed in the infrared-active bands at 345, 267 and 242 cm-1. These bands have been assigned to Ca-O antisymmetric stretching vibrations. The Raman-active bands at 305, 158 and 111 cm-1 have been assigned to Ca-O symmetric stretching vibrations with no displacement of the calcium atom. The result of a normal coordinate analysis is consistent with both the empirical assignments and the experimental isotope shifts. These results indicate that Ca-ligand bond forces are almost similar to those of copper- and zinc-amino acid complexes.
