摘要：
The infrared and Raman spectra of the Zn(NH3)(2)Br-2 complex in the higher and lowest infrared region (600-40 cm(-1)) have been assigned by using N-15 and H-2 isotopic substitution and were compared with the analogous Zn(NH3)(2)Cl-2 complex. The principal nu(s)(ZnN) (alpha(1)), nu(as)(ZnN) (b(1)), nu(s)(ZnBr) (alpha(1)) and nu(as)(ZnBr) (b(2)) stretching and the delta(NZnBr) bending modes were observed. A normal coordinate analysis for the three isotopic compounds has been carried out based on a local symmetry force field (LSFF). The results support the experimental assignments.
