Metal isotope effect on the Raman spectrum of solid [Zn(NH3)4]I2

Abstract
The A1 and F2 Zn–N stretching vibrations of the Raman spectrum of solid [Zn(NH3)4]I2 have been assigned by using the metal isotope technique: the A1 mode shows almost no dependence on the isotopic substitution of the central metal atom, whereas the F2 mode is metal isotope-sensitive.
